Abstract:
The optical properties of Eu[Formula: see text] ions in tellurite glass ceramics with the chemical composition 50TeO2–29B2O3–10ZnO–10Na2O–1Eu2O3-based precursor glasses were presented. These precursor glasses have been prepared by melt quenching method in air, followed by thermal annealing at 550[Formula: see text]C for 12 h, 24 h and 36 h. After thermal annealing process, the micro–crystals appeared in host tellurite glasses. Judd–Ofelt (JO) parameters were calculated from the photoluminescence (PL) spectral measurements. The [Formula: see text], [Formula: see text] and [Formula: see text] parameters have been used to estimate the radiative properties of Eu[Formula: see text] ions in tellurite glass ceramics such as transition probabilities, branching ratio, radiative lifetimes and stimulated emission cross-section. The results of tellurite glass ceramic have been discussed and compared with the similar studies.

Abstract:
Systematic series of binary zinc tellurite glasses in the form(ZnO)x(TeO2)(wherex=0to 0.4 with an interval of 0.05 mole fraction) have been successfully prepared via conventional melt cast-quenching technique. Their density was determined by Archimedes method with acetone as buoyant liquid. The thermal expansion coefficient of each zinc tellurite glasses was measured using L75D1250 dilatometer, while their glass transition temperature (Tg) was determined by the SETARAM Labsys DTA/6 differential thermogravimetric analysis at a heating rate of 20 K min−1. The acoustic Debye temperature and the softening temperature (Ts) were estimated based on the longitudinal (VL) and shear ultrasonic (Vs) wave velocities propagated in each glass sample. For ultrasonic velocity measurement of the glass sample, MATEC MBS 8000 Ultrasonic Data Acquisition System was used. All measurements were taken at 10 MHz frequency and at room temperature. All the thermal properties of such binary tellurite glasses were measured as a function of ZnO composition. The composition dependence was discussed in terms of ZnO modifiers that were expected to change the thermal properties of tellurite glasses. Experimental results show their density, and the thermal expansion coefficient increases as more ZnO content is added to the tellurite glass network, while their glass transition, Debye temperature, and the softening temperature decrease due to a change in the coordination number (CN) of the network forming atoms and the destruction of the network structure brought about by the formation of some nonbridging oxygen (NBO) atoms.

Abstract:
Modifying the structural and optical properties of inorganic glasses via controlled doping of various rare earth ions by inhibiting the quenching effect is a challenging task. We report the influence of samarium (Sm3+) ions concentration on enhanced optical properties of tellurite glass. A series of glasses with composition (0.80-x)TeO2 + 0.10Li2O + 0.10 Na2O + xSm2O3, where 0.0<x <0.03 mol% are prepared using melt quenching method and optical characterizations are performed. The XRD spectra confirm the amorphous nature of the glass. The Urbach energy decreases and the optical gap for both direcet and indirect transitions increases with the increse of samerium contents. The UV-Vis spectra comprised of eight absorption bands and PL spectra reveal four prominet peaks corresponding to various transitions from the ground state to the excited states of Sm3+ ion. The optical response shows significant enhancement with increasing concentration of samerium ions. Our detail experimental analyses may be useful for the development of tellurite glass based photonic devices. Keywords: Tellurite Glass, Sm3+ ions, Urbach Energy, Direct and Indirect Transition.

Abstract:
Investigation on green emission and spectral intensity of tellurite based glass containing erbium oxide NPs is one of the crucial issues. Tellurite based glass containing erbium oxide NPs with the composition of{[(TeO2)0.70(B2O3)0.30]0.7(ZnO)0.3}0.95(Er2O3)0.05has been prepared by using conventional melt-quenching method. The structural and optical properties of the glass sample were characterized by using XRD, FTIR, UV-Vis absorption, and PL spectroscopy. The amorphous structural arrangement was proved through XRD method. The formation of TeO3and BO3units was revealed by FTIR analysis. Five transition states of excitation were shown in UV-Vis spectra which arise from the ground state4I15/2to the excited states4G11/2+2H9/2+4F5/2+4F7/2+2H11/2+4S3/2+4F9/2+4I9/2+4I11/2. The intensity parametersΩt(t=2, 4, 6) are calculated and follow the trend ofΩ2>Ω4>Ω6. Broad green emission at 559 nm under 385 nm excitation was obtained.

Abstract:
TeO2-based glasses have attracted growing attention due to their unique combination of properties (e.g., high refractive index, visible-to-infrared transparency window, high rare-earth solubility), which are promising for a wide range of applications. This thesis presents a mechanistic study on the relationship between glass-structure and properties of TeO2-based glasses with the aim of (i) enhancing visible transparency of TeO2-ZnO-Na2O (TZN) glass film and (ii) understanding ionic conductivity of TeO2-Na2O-NaX (TNN) glass system with X=Cl, Br, I. The first focus of this thesis is driven by the notorious issue that metallic-Te formed in TZN solgel films deteriorates the transparency. Previous research has revealed that metallic-Te is formed due to the chemical reduction of Te4+ to Te0 during the synthesis process. Applying O2 rich atmosphere during the thermal treatment (for converting organic sol to inorganic TZN glass) can suppress the formation of metallic-Te. However, the complete prevention of metallic-Te formation has not been achieved to date. In this thesis, the research on non-hydrolytic sol-gel (NHSG) process of making TZN transparent glass film elucidates the mechanism of metallic-Te formation, which reveals the use of O2 combined with a longer sol aging time (30~60 days) and an optimized sol heating temperature (150 oC) can completely prevent the formation of metallic-Te. The TZN glass film prepared via this optimized protocol has a transmission close to the theoretical limit. The achievement of high-transparent TeO2-based glass film paves the way to develop hybrid optoelectronic films by incorporating diverse nanoparticles with unique functionalities. The second part of this thesis focuses on ionic conductive glasses that rely on the migration of mobile alkali (sodium or lithium) ions. The conductivity of such glasses is determined by the concentration and mobility of mobile alkali ions. The research on traditional oxide glasses (SiO2- , B2O3, P2O5-based) has revealed that the incorporation of halides enhances the conductivity. This thesis investigates the impact of halides on the conductivity of the less-explored glass system, which is TNN glasses with varied (type and concentration) NaX. The conductivity depends on the mobility and concentration of the mobile ions. This research reveals the increase of free volume with increasing NaX concentration, which suggests an increase of space for ion migration thus mobile ion mobility. The Raman spectra confirm the expansion of glass network caused by the introduced NaX. The conductivities of NaCl and NaBr containing glasses remain constant while the mobile ion mobility increases with increasing NaCl or NaBr concentration, which infers a decrease of mobile Na+ ion concentration. The conductivity of NaI containing glasses significantly increases with increasing NaI concentration, which suggests an increase of mobile Na+ ion concentration in addition to the increase of the mobility. This research achieved the enhancement of conductivity while maintaining a good transparency of TeO2-based glasses. In addition, the mechanistic understanding of the relationship of halides, glass-structure and conductivity is a valuable guidance to the future research on ionic conductive glasses.

Abstract:
Transparent glasses embedded with TTB structured ferroelectric nano/micro crystals (K3Li2Nb5O15, Ba5Li2Ti2Nb8O30) were fabricated in various tellurite and borate based glass matrices and characterized for their physical properties. Nanocrystals of K3Li2Nb5O15 were successfully grown inside tellurite glass matrix via conventional heat-treatment route. Eventhough, tellurite glasses preferentially crystallize only on the surface, bulk uniform crystallization was achieved in the (100-x) TeO2 - x(1.5K2O-Li2O-2.5Nb2O5) system. Heat capacity studies revealed them to be thermodynamically less fragile than any other tellurite glasses ever reported in the literature. Pyroelectric and ferroelectric effects as well as second harmonic generation were demonstrated for the heat treated (glass nanocrystal composites) samples in this system. The conventional method of melt-quenching of constituent oxides could not yield Ba5Li2Ti2Nb8O30 crystallites. So, Ba5Li2Ti2Nb8O30 microcrystals were successfully formed in tellurite glass matrix by mixing pre-reacted Ba5Li2Ti2Nb8O30 ceramic powders with TeO2. The glass transition temperature was found to be the highest ever reported and this system was kinetically strong based on the fragility parameter. Dielectric studies revealed a frequency and temperature independent nature of the dielectric constant and very low dielectric loss. The SHG measurement which was carried out as a function of temperature demonstrated the incidence of blue second harmonic generation in the microcrystals present in the glass matrix. Ba5Li2Ti2Nb8O30 nanocrystals were successfully crystallized in the transparent glass system (100-x)Li2B4O7 – x(Ba5Li2Ti2Nb8O30). Dielectric constant increased while the dielectric loss decreased with the increase in Ba5Li2Ti2Nb8O30 content. Nuclear magnetic resonance spectroscopic studies were carried out to have an insight into the structure of this system. Transmission studies and refractive index measurements were performed and various optical parameters were calculated. Dielectric and transport properties were studied for the glasses and glass nano/microcrystal composites of all the systems reported in this thesis. Li+ ion was found to be responsible for conduction in all these systems. Evolution of self-organized nanopatterns of K3Li2Nb5O15 crystals has been demonstrated in the glass system (100-x) TeO2 - x(1.5K2O-Li2O-2.5Nb2O5) by excimer laser irradiation. The second harmonic signal observed by the Maker fringe technique has been attributed to the presence of well-aligned nano-sized grating structures in the glass system. Glasses belonging to the systems TeO2-K3Li2Nb5O15, TeO2-Ba5Li2Ti2Nb8O30 and V2Te2O9 undergo spinodal decomposition on exposing to KrF pulsed excimer laser. The spinodally phase separated structures were observed on all the surfaces of the samples. Ring shaped patterns were observed on several locations of the samples at higher frequency of laser pulses probably owing to the shock waves produced by the high intense laser beam. Line shaped patterns were found to originate on the sample surfaces when irradiated for longer periods.
