Abstract:

In order to solve the problem of environmental health hazards caused by phthalate esters, a series of pure Bi2O2CO3 and light (La, Ce, Pr, Nd, Sm and Eu) and heavy (Gd, Tb, Dy, Ho, Er, Tm, Yb and Lu) rare earth-doped Bi2O2CO3 samples were prepared by hydrothermal method. The crystalline phase composition and physical structure of the samples calcined at 300 °C were studied, and we found that the rare earth ion doping promoted the transformation of Bi2O2CO3 to β-Bi2O3 crystalline phase, thus obtaining a mixed crystal phase photocatalyst constituted by rare earth-ion-doped Bi2O2CO3/β-Bi2O3. The Bi2O3/Bi2O2CO3 heterostructure had a lower band gap and more efficient charge transfer. The fabricated samples were applied to the photocatalytic degradation of dimethyl phthalate (DMP) under a 300 W tungsten lamp, and it was found that the rare earth ion doping enhanced the photocatalytic degradation activity of DMP, in which the heavy rare earth of Er-doped sample reached 78% degradation for DMP at 150 min of light illumination. In addition, the doping of rare earths resulted in a larger specific surface area and a stronger absorption of visible light. At the same time, the formation of Bi2O2CO3/β-Bi2O3 heterogeneous junction enhanced the separation efficiency of photogenerated electrons and holes.

Abstract:

Zinc oxide (ZnO) nanowires were grown via thermal transport and subsequently doped with different concentrations of Tm, Yb, and Eu using ion implantation and post annealing. High ion fluences lead to morphology changes due to sputtering; however, freestanding nanowires become less damaged compared to those attached to substrates. No other phases like rare earth (RE) oxides were detected, no amorphization occurs in any sample, and homogeneous doping with the desired concentrations was achieved. Photoluminescence measurements demonstrate the optical activation of trivalent RE-elements and the emission of the characteristic intra-4f-luminescence of the respective RE atoms, which could be assigned according to the Dieke-diagram. An increasing RE concentration results into decreasing luminescence intensity caused by energy transfer mechanisms to non-radiative remaining implantation defect sites. Furthermore, low thermal quenching was observed due to the considerable wide band gap of ZnO.

Abstract:

Rare earth (R) ion-doped TiO2 nanocomposites (NCs) with general composition (R: Y, Yb, Gd; , 0.2) were synthesized through co-precipitation/hydrolysis (CPH). NC particles with average size of approximately a few tens of nm were obtained. Similar compositions of polycrystalline (PC) samples with larger particle size were also prepared employing solid state reaction (SSR) method. Visible light photocatalytic activity of all samples was investigated for degradation of Congo red (CR) dye. Both in terms of apparent rate constant () and percent degradation after 180 min (), all NCs produced significantly enhanced degradation as compared to pure TiO2 and PC samples. Best degradation of 95% ( value) resulted with composition of Y3+ doped NC with min−1. This was followed by of 85 and 80%, produced with Yb3+ and Gd3+ doped, NCs, at around and min−1, respectively. The observations clearly suggest that enhanced photocatalytic degradation of CR is directly related to smaller particle size of the catalysts. Moreover, the presence of rare earth ions in the composites facilitates further improvement of degradation efficiency through effective suppression of recombination.

Abstract:

A great deal of theoretical activity has resulted from blending the fields of computer science and quantum mechanics. Out of this work has come the concept of a quantum computer, which promises to solve problems currently intractable for classical computers. This promise has, in turn, generated a large amount of effort directed toward investigating quantum computing experimentally. ¶ Quantum computing is difficult because fragile quantum superposition states of the computers register must be protected from the environment. This is made more difficult by the need to manipulate and measure these states. ¶ This thesis describes work that was carried out both to investigate and to demonstrate the utility of rare earth ion dopants for quantum computation. Dopants in solids are seen by many as a potential means of achieving scalable quantum computing. Rare earth ion dopants are an obvious choice for investigating such quantum computation. Long coherence times for both optical and nuclear spin transitions have been observed as well as optical manipulation of the spin states. The advantage that the scheme developed here has over nearly all of its competitors is that no complex nanofabrication is required. The advantages of avoiding nano-fabrication are two fold. Firstly, coherence times are likely to be adversely effected by the damage to the crystal structure that this manufacture represents. Secondly, the nano-fabrication presents a very serious difficulty in itself. ¶ Because of these advantages it was possible to perform two-qubit operations between independent qubits. This is the first time that such operations have been performed and presents a milestone in quantum computation using dopants in solids. It is only the second time two-qubit operations have been demonstrated in a solid. ¶ The experiments performed in this thesis were in two main areas: The first was the characterisation of hyperfine interactions in rare earth ion dopants; the second, simple demonstrations directly related to quantum computation. ¶ The first experiments that were carried out were to characterise the hyperfine interactions in Pr[superscript 3]+:Y[subscript 2]SiO[subscript 5]. The characterisation was the first carried out for the dopants in a site of such low symmetry. The resulting information about oscillator strengths and transition frequencies should prove indispensable when using such a system for quantum computation. It has already enabled an increase in the coherence times of nuclear spin transitions by two orders of magnitudes. ¶ The experiments directly related to the demonstration of quantum computation were all carried out using ensembles. The presence of a significant distribution of resonant frequencies, or inhomogeneous broadening, meant that many different sub-ensembles could be addressed, based on their resonant frequencies. Furthermore, the properties of the sub-ensembles could be engineered by optically pumping unwanted members to different hyperfine states away from resonance with the laser. ¶ A previously demonstrated technique for realising ensembles that could be used as single qubits was investigated and improved. Also, experiments were carried out to demonstrate the resulting ensembles utility as qubits. Further to this, ions from one of the ensembles were selected out, based on their interaction with the ions of another. Elementary two qubit operations were then demonstrated using these ensembles.

Abstract:

Three kinds of oxide glasses doped with Er3+ ions were chosen for investigation. Both the properties of glass and fluorescence from rare earth dopant ions are measured and discussed. In Er3+ ion doped silicate glass, the changes in the structure of glass as a result of fluorine addition are studied by measuring the glass properties: density, molar volume, refractive index, IR and UV edges. The absorption and emission cross- sections of Er3+ ion increase with increasing value of F/O ratio as do the full width of half maximum (FWHM) and figure-of-merit (FOM) for gain and bandwidth. In Er3+ ion doped heavy metal germanate glass, the structural units of forming network in germanate glass change with the addition of PbO, Bi2C>3, Ga2C>3 and TeC>2. The molar volume, glass transition temperature Tg, IR and UV edges have been measured and discussed with the relation of glass structure. More Er3+ ion sites result in the increase of absorption and emission cross-sections, emission FWHM and FOM for gain. In Er3+ doped Te02 - ZnO - R2O (R2O = Li20, Na20 and K2O) tellurite glass system, glass properties such as density, molar volume, transition temperature Tg, IR and UV edges are measured and discussed. The glass structure has been characterised using Raman spectra. The role of F' and Cl' has also been studied in tellurite glass. Crystallisation kinetics has been analysed in tellurite glass using isothermal and non- isothermal methods. The properties of Er3+ absorption and emission have been measured and discussed with the change of glass structure and concentrations. FOM for gain and bandwidth have also been compared and discussed in Er3+ doped modifies silicate, HMO germanate, tellurite and ZBLAN fluoride glasses. The tellurite glass fibre has been made and the emission spectra of Er3+ ion in fibre have been measured. Absorption and emission spectra have been studied in Tm -doped tellurite glass, it shows to be a highly promising host for a 1.47 (im amplifier capable of providing extended short-wavelength gain and a continuous band with the tellurite EDFA. Nd3+- doped tellurite and silicate glasses have also been studied, amplifier operating around 1.34 (j.m is clearly desirable in tellurite glass. A continuous gain band extending from 1310 to 1600 nm may become possible by using Nd3+, Tm3+ and Er3+ amplifiers.

Abstract:

This Project is aimed at developing rare earth ion doped chalcogenide glasses targeting mid-infrared (MIR) fibre lasers, emitting in the wavelength region 4 - 5 μm. The work reported in this thesis has two objectives: (i) a study of the Ge-As-In-Se glass system when doped with a single species of rare earth (RE) ions, i.e. praseodymium (Pr3+) or cerium (Ce3+), or when co-doped with two rare earth ion species: Pr3+ and Ce3+, and (ii) a study of the effect of replacing a gallium (Ga) additive with an indium (In) additive on the physical and optical properties of the undoped and Pr3+ doped Ge-As-(Ga/In)-Se glasses and fibres. The MIR, i.e. 3 - 25 μm wavelength, offers to advance many photonics areas including bio-medical imaging spectroscopy for human tissue sensing in vivo for early cancer diagnosis. Low loss RE-ion doped MIR fibre lasers are potential pumps for MIR supercontinuum generation (SCG) sources for a compact MIR broadband device. Also, MIR fibre narrowband lasers offer potential new wavelengths for laser medical surgery. To date, there are no MIR rare earth ion doped glass fibre lasers emitting at wavelengths ≥ 4 μm. Selenide (Se)-based glasses, a member of the chalcogenide glass family, are known for their wide transparency up to 12 μm and good rare earth ion solubility. In the Project, an additive to the Ge-As-Se glass system of indium or gallium is considered to help decluster the rare earth ions and increase their solubility in the as-prepared Pr3+ doped Ge-As-(Ga/In)-Se glasses. However, an indium additive is concluded here to achieve a lower rare earth ion solubility limit than that obtained using the equivalent gallium additive in the Ge-As-(Ga/In)-Se glass systems. On the other hand, the photoluminescent intensity is concluded here to be approximately doubled when using an indium additive in Pr3+ doped Ge-As-In- Se, compared to the analogous gallium glasses. Furthermore, the decay lifetime, at the same emission wavelength of 4.7 μm, is found to be longer in the Pr3+ doped Ge-As-In-Se glasses when compared to the Pr3+ doped Ge-As- Ga-Se glasses. Overall, for a singly-doped Ge-As-In-Se glass system, Pr3+ offer wide photoluminescence spectral emission in the range 3 - 6 μm, which promotes this type of glass fibre as an active source for MIR laser emission in the target range of 4 - 5 μm. However, the photoluminescent decay lifetime, at 4.7 μm, of Pr3+ doped Ge-As-In-Se is concluded to decrease substantially with the number of thermal processes invoked to fabricate the glass-based fibres; a lifetime of 7 - 9 ms measured on the as-prepared fibres is compared to the decay lifetime of 9 - 10.1 ms that were found in the bulk glasses. Alternatively, the addition of Ce3+ in the Ge-As-In-Se glass system is concluded to offer a larger absorption cross-section than that of the Pr3+ in the wavelength range 3.5 - 5 μm. Co-doping the Pr3+ / Ce3+ in Ge-As-In-Se in order to enhance the MIR photoluminescence emission in the range 3 - 6 μm is also investigated. It is concluded that rare earth ions, in particular Ce3+ and / or Pr3+, doped chalcogenide glass fibres based on the Ge-As-In-Se glass system, developed through this Project, are strong candidates towards achieving MIR fibre lasers.

Abstract:

Aux basses températures, les matrices dopées aux ions terre-rare sont des systèmes prometteurs pour la réalisation de mémoires quantiques. Parmi elles, le système Er³⁺:Y₂SiO₅ a l'avantage de posséder une transition aux longueurs d'onde Télécom, adaptée aux réseaux de communication actuels. Cependant, aucun stockage quantique n'a pu être réalisé de manière efficace durant un temps suffisamment long dans ce matériau. L'objectif de cette thèse est de mieux comprendre les interactions limitant la cohérence du système aux faibles champs magnétiques. Dans ce cadre là, les interactions dominantes sont les basculements réciproques entre deux spins électroniques opposés des ions erbium et l'interaction super-hyperfine entre ces spins et les spins nucléaires des ligands yttrium. J'ai calculé la force et les caractéristiques de ces deux couplages dipolaires en incluant la grande anisotropie de la matrice Y₂SiO₅. J'ai alors pu vérifier l'effet de cette anisotropie sur les basculements réciproques des spins des ions erbium à l'aide de deux techniques optiques, le creusement de trou spectral et l'excitation transitoire. Le taux de ces basculements est maximisé lorsque le champ magnétique est orienté perpendiculairement à l'axe principal du tenseur caractérisant le spin effectif. Il augmente globalement comme le carré de la concentration en ions dopants et diminue avec le champ magnétique. Enfin, j'ai pu mesurer les caractéristiques des interactions super-hyperfines par le biais des modulations d'une décroissance d'écho de photon qu'elles provoquent. Il existe une configuration particulière où un couplage sélectif intervient entre les ions erbium et un unique yttrium de leurs environnements. Au contraire, le couplage à un nombre important d'ions ligands est responsable de la chute du temps de cohérence pour des champs magnétiques inférieurs à la dizaine de mT
At low temperatures, rare-earth doped matrices are promising supports for the development of quantum memories. Among them, Er³⁺:Y₂SiO₅ is well adapted to the current communication networks because of its transition at Telecom wavelength. However, quantum storage has a very limited efficiency and a short duration in this material. In this thesis, I study the interactions that hinder the coherence at low magnetic fields. In this regime, the dominant processes are flip-flops between opposite electronic spins of erbium ions and the super-hyperfine interaction with nuclear spins of yttrium ligands. I have included the strong anisotropy of the Y₂SiO₅ matrix in the calculation of these two dipolar interactions. In order to check the anisotropy of the flip-flops between erbium spins, I have used two different optical techniques : spectral hole-burning and transient excitation. I have showed that their rate is maximum when the magnetic field is perpendicular to the principal axis of the effective spin tensor. Moreover, the flip-flop probability globally increases as the square of the doping concentration and as the inverse of the field. Then I have also checked the calculations of super-hyperfine interactions by measuring photon echo modulations. I have found a particular situation where an erbium ion is strongly coupled to a single yttrium. On the contrary, the coupling to several ligands at very low magnetic fields drastically reduces the coherence time

Abstract:

Research into rare-earth ion doping of silica based optical fibres is described and a detailed study of the fabrication process reported. Dilute solutions of rare-earth ions are employed to incorporate dopants into preforms prepared by conventional methods. Alternative core glass compositions are also studied. Parameters affecting dopant incorporation, host composition and refractive index, as well as impurity concentration are investigated. Spectroscopic fluorescence and absorption measurements are presented and provide important information for device applications. In addition, fluorescence lifetime data allow the effect of dopant concentration and host composition to be analysed. Thus, a model describing the limits of doping levels is developed. The use of rare-earth ion doped fibre in several devices, both active and passive, is assessed, with special reference to the fabrication process. In particular, the effect of host glass on the laser characteristics of Tm3+ doped fibres and of the ratio of doping levels on the behaviour of Er3+/Yb3+ codoped fibre lasers is discussed. A practical temperature sensor based on fibre doped with low levels of rare-earth ions and a fibre filter requiring heavily doped fibre are demonstrated, with suggested design for improved performance. Finally, a novel radiation dosimeter, based on Nd3+ doped fibre, is described. Unusually, the response is found to be both rereadable and linear, even at elevated temperatures, and a model is proposed to describe the behaviour of this material. In summary, the fabrication, characterisation and applications of a wide range of rare-earth ion doped optical fibres have been investigated in detail.

nReVO4:Eu3+ (Re Gd, Y, Sm, La) luminescent nanocrystals of different shape and size from 2 to 300 nm have been synthesized. Luminescence of nReVO4:Eu3+ nanocrystals are effectively excited under UV and visible irradiation. By means of luminescence microscopy and luminescence microspectroscopy it has been revealed that spherical nanocrystals with an average diameter from 3 to 20 nm tend to accumulate mainly in the isolated rat hepatocyte nuclei. Spherical nGdYVO4:Eu3+ nanocrystals are efficient inorganic markers and can be used in systems of selective delivery of substances into the cell nucleus.

Abstract:

Rare-earth-doped integrated optic waveguide lasers have been demonstrated in glass, LiNbO3, and other host materials. This technology offers a variety of new components that include diode-pumped amplifiers and lasers. The planar geometry is particularly attractive because selective doping permits the integration of passive and active devices on the same substrate and it is also compatible with pumping by laser diodes. Ion exchanged channel waveguides have been demonstrated to lase near 1060 nm and 1320 nm in Nd-doped silicate and Nd-doped phosphate glass, respectively. Nd-doped waveguide lasers have also been fabricated by chemical vapor deposition; Er-doped waveguide lasers have been similarly fabricated. Y-branch splitters with gain at 1060 nm have been reported in Nd-doped silicate glass waveguides. Ion implantation has been used to form waveguides in Nd-doped YAG and Nd-doped GGG. Nd and Er-doped LiNbO3 waveguide lasers operating near 1060 nm and 1550 nm, respectively, have also been reported. Attempts have been made to demonstrate visible upconversion lasing in Er-doped LiNbO3 and LiTaO3 waveguides. We will review the status of this technology and also highlight some of the more promising applications.

Abstract:

Rare-earth-doped glass waveguides are suitable for the fabrication of stable and low-threshold lasers in both the visible and infrared regions.1 We have investigated potassium, silver, and cesium ion-exchange to produce neodymium- and erbium-doped glass channel waveguides. We studied two configurations. In the first configuration, the waveguides were produced in a commercially available rare-earth-doped substrate. In the second, a waveguide was made in an undoped glass. Then, it was spin coated with a rare-earth-doped phosphate layer. Channel waveguides with different dimensions were produced, and the propagation losses as well as the absorption and emission spectra of these waveguides were determined.

Abstract:

Diode laser pumped, room temperature upconversion lasers are one possible route to ail solid-state visible wavelength laser devices. Room temperature, upconversion laser operation has been obtained by using barium yttrium fluoride doped with either thulium or erbium ions, and sensitized with ytterbium. The 960 nm output from a titanium sapphire laser or diode laser serves as the pump source. Excitation is accomplished by means of energy transfer from ytterbium to the active ion. Successive transfers of energy from ytterbium to the active ion, as well as cross-relaxation processes among the active ions, distribute the energy to the various excited states responsible for the laser emission. Laser operation has been obtained at wavelengths in the red, green, and blue regions of the visible spectrum. Several of these transitions are capable of cw operation. A discussion of the pumping processes and recent results will be presented.

Abstract:

Multivalent rare earth ion, Sm+2/Sm+3 was incorporated into aluminosilicate glass fiber using an aerosol delivery technique. Co-doping of trivalent and divalent states of the ions has been spectroscopically confirmed. Irradiated by multi-line CW Ar ion laser of 1 Watt, the fiber showed photoinduced refractive change of 7.6 × 10−5. Bleaching of Sm+2 absorption band was also observed. Photoionization of Sm+2 is believed to be a main cause of the photosensitivity.

Abstract:

The nature of inhomogeneous broadening in rare earth systems plays an important role in the dynamical optical properties of ions in crystals. For this reason much of the work on the nature of the inhomogeneous broadening in rare earth doped systems has concentrated on the investigation of ion-ion interactions such as spectral transfer and up conversion processes.1,3 Variations in homogeneous optical dephasing times across the inhomogeneous optical line have also been reported.4 These studies concentrate on the variations of collective effects of ion- ion interactions at different positions in the inhomogeneous optical line in relatively heavily doped rare earth systems. We report variations in optically detected NQR (ODNQR) linewidths and shifts of Pr3+ hyperfme transitions in the optical ground state as a function of position in the inhomogeneous optical line and for satellite transitions of the 1D2-3H4 transition in lightly doped (0.5 at. %) Pr3+:LaF3.
