Abstract:

Solid assemblies of carbon quantum dots (CQDs) are important for diverse applications including LEDs, solar cells, and photosensors; their optical and electrical properties have not been explored yet. Herein, we used amphiphilic CQDs synthesized from citric acid and thiourea by a solvothermal method to fabricate CQD solid films. Optical properties of CQDs studied by UV-Vis and photoluminescence spectroscopies indicate that CQDs possess three different emission centers at 425 nm, 525 nm, and 625 nm originating from C sp2 states, N-states, and S-states, respectively. In a solid state, π-π stacking quenched the blue emission, while the red emission increased. Importantly, CQD films exhibited excitation independence, which is important to design solid-state lighting applications.

Abstract:

Purpose This study aims to fabricate and manipulate ensemble spin of negative nitrogen-vacancy (NV−) centres optimally for future solid atomic magnetometers/gyroscope. Parameters for sample preparation most related to magnetometers/gyroscope are, in particular, the concentration and homogeneity of the NV− centres, the parameters’ microwave antenna of resonance frequency and the strength of the microwave on NV− centres. Besides, the abundance of other impurities such as neutral NV centres (NV0) and substitutional nitrogen in the lattice also plays a critical role in magnetic sensing. Design/methodology/approach The authors succeeded in fabricating the assembly of NV centres in diamond and they determined its concentration of (2-3) × 1016 cm−3 with irradiation followed by annealing under a high temperature condition. They explored a novel magnetic resonance approach to detect the weak magnetic fields that takes advantage of the solid-state electron ensemble spin of NV− centres in diamond. In particular, the authors set up a magnetic sensor on the basis of the assembly of NV centres. They succeeded in fabricating the assembly of NV centres in diamond and determined its concentration. They also clarified the magnetic field intensity measured at different positions along the antenna with different lengths, and they found the optimal position where the signal of the magnetic field reaches the maximum. Findings The authors mainly reported preparation, initialization, manipulation and measurement of the ensemble spin of the NV centres in diamond using optical excitation and microwave radiation methods with variation of the external magnetic field. They determined the optimal parameters of irradiation and annealing to generate the ensemble NV centres, and a concentration of NV− centres as high as 1016 cm−3 in diamond was obtained. In addition, they found that sensitivity of the magnetometer using this method can reach as low as 5.22 µT/Hz currently. Practical implications This research can shed light on the development of an atomic magnetometer and a gyroscope on the basis of the ensemble spin of NV centres in diamond. Social implications High concentration spin of NV− in diamond is one of the advantages compared with that of the atomic vapor cells, because it can obtain a higher concentration. When increasing the spin concentration, the spin signal is easy to detect, and macro-atomic spin magnetometer become possible. This research is the first step for solid atomic magnetometers with high spin density and high sensitivity potentially with further optimization. It has a wide range of applications from fundamental physics tests, sensor applications and navigation to detection of NMR signals. Originality/value As has been pointed out, in this research, the authors mainly worked on fabricating NV− centres with high concentration (1015-1016 cm−3) in diamond by using optimal irradiation and annealing processes, and they quantitatively defined the NV− concentration, which is important for the design of higher concentration processes in the magnetometer and gyroscope. Until now, few groups can directly define the NV− concentration. Besides, the authors optimized the microwave antenna parameters experimentally and explored the dependence between the splitting of the magnetic resonance and the magnetic fields, which dictated the minimum detectable magnetic field.

Abstract:

Organo metal halide perovskites are solution processed semiconductors that recently attracted a great attention. They possess a rather “soft” and (photo) chemically active solid structure allowing for ion migration and other mass diffusion processes. This is a likely reason why non-radiative recombination centres in these materials are activated and deactivated on relatively slow time-scales. This dynamics reveals as photoluminescence (PL) fluctuations (blinking) of individual microcrystals and local areas of films and allows for application of a broad range of single molecule spectroscopy methods including optical super-resolution. Studying PL blinking resolves properties of individual non-radiative centres and helps to unravel their chemical nature.

Abstract:

Abstract Van der Waals forces are of short range. In molecular crystals the interacting atoms or groups of atoms of a molecule are fixed in their position with respect to the atoms of the neighboring molecules. From measurements of the intermolecular interactions via properties which can be assigned to the individual atoms (groups), such as hyperfine interactions or vibrational frequencies, as a function of the intermolecular distances, the van der Waals (vdW) potentials may be evaluated. We propose the use of discrete changes of intermolecular distances for studying vdW-interactions, the method of “Several Solid States”, a) by combining a molecule A with different moleculs Bi, in stoichiometric proportions and in a crystallographically ordered way to molecular solid complexes; b) by investigating the changes of atomic (group) properties in systems with two ore more solid phases appearing in the phase diagram as a function of temperature (pressure). This way of using several solid states is offered only by chance; c) by using the fact that in many molecular solids there is more than one molecule in the asymmetric unit of the elementary cell in the crystal structure, and therefore several vdW-potentials for chemically identical intermolecular neighbors; d) by the synthesis of compounds containing the atoms (groups), the vdW-interactions of which one wants to study, with one or more centers of chirality. With one center of asymmetry in the molecule one finds the molecule considered in two different situations of vdW-contacts at least, and, in first approximation, one can assume identical intramolecular interactions (besides the optical activity). Two chirality centers within the molecule lead to three (at least) different crystal fields: a) (±); b) (− −) respectively (+ +); c) (− −, + +). Examples of hyperfine interaction studies, based on this "Several Solid States" concept are discussed.

Abstract:

In the present work the temperature dependence of the work function of oxide cathodes in operating fluorescent lamps was investigated experimentally. A detailed review on the theory is presented, including a thermodynamic and a quantum mechanical view on the problem. Aspects such as the role of the electrochemical potential, external and internal potentials, the constituents of the electron affinity, the patch effect and surface states are discussed. For solids in contact the Volta and Galvani potentials are related to their work functions. The importance of colour centres in oxide electrodes on the temperature dependence of the work function and the impact of ultraviolet radiation is emphasized. The measurements have been carried out under zero field emission of electrons from the electrode, using the Waymouth (rf) and Eisenmann (visual) methods as indicators. By inserting an empirical ansatz into the Richardson equation, it was possible to determine the temperature dependence of the work function from the experiments.

Abstract:

Interactions between well-mixed fine powders of As2O3, P2O5, MoO3, WO3 and Nb2O5 at different stoichiometry in quartz ampoules under vacuum at ~1000 °C in the presence of metallic molybdenum (or niobium), over several weeks, led to shiny dichroic crystalline materials being formed in cooler parts of the reaction vessel. An addition of small quantities of metals-Mo or Nb-was made with the aim of partially reducing their highly oxidized Mo(VI), W(VI) or Nb(V) species to corresponding Mo(V), W(V) and Nb(IV) centers, in order to form mixed valence solids. Sublimed crystals of four new compounds were investigated using a variety of techniques, with prime emphasis on the X-ray analysis, followed by spectroscopy (diffusion reflectance, IR, Raman and EPR), second harmonic generation (SHG), thermal analysis under N2 and air atmosphere, and single crystals electrical conductivity studies. The results evidenced the formation of new complex solids of previously unknown compositions and structures. Three out of four compounds crystallized in non-centrosymmetric space groups and represent layered 2D polymeric puckered structures that being stacked on each other form 3D lattices. All new solids exhibit strong second-harmonic-generation (SHG effect; based on YAG 1064 nm tests with detection of 532 nm photons), and a rare photosalient effect when crystals physically move in the laser beam. Single crystals’ electrical conductivity of the four new synthesized compounds was measured, and the results showed their semiconductor behavior. Values of band gaps of these new solids were determined using diffusion reflectance spectroscopy in the visible region. Aspects of new solids’ practical usefulness are discussed.

Abstract:

Today ionic crystals are widely used in devices for various purposes. In X-ray spectral optics they are widely used as crystal monochromators; ionic crystals are used in optical devices where lenses and transparent optical media (light filters) are made of optically pure materials - ionic crystals. In general, the main positive feature of these materials is transparency regarding the transmission of radiation in the visible region of the spectrum (transmittance of about 0.9) and neutrality - that is, approximately the same reaction of the medium to different spectral ranges of radiation. Ionic crystals are also widely used in detectors (scintillators, ionizing radiation dosimeters) and lasers. They are also widely used in acousto-optics and electrical engineering (lines of electrical signals delay, which gain efficiency due to the relatively small absorption of ultrasonic waves, and, therefore, it is possible to work with a wide sequence of signals probing the crystal). It is known that when ionizing radiation passes through ionic crystals, color centers appear in them, which can change the spectral composition of radiation both in the UV region and in the visible range. For example, the simplest configurations of color centers (F-centers) lead to the appearance in optical materials of additional absorption bands localized on the wavelength axis with a maximum at the wavelength lmax = 248 нм , but more complex configurations of radiation damage in solids already lead to the appearance of absorption bands at wavelengths in the visible range. This already presents some difficulties for developers and designers of relevant equipment, as changes in the spectral composition of radiation passing through the optical system of the device can lead, for example, to loss of efficiency of the selected radiation receiver, the main characteristic of which is primarily spectral sensitivity. Taking into account possible changes in the spectral composition of radiation is an important and urgent task of modern optical instrumentation. The purpose of this work is the analysis and justification of a method that takes into account structural changes in externally irradiated ionic crystals.

Abstract:

Population transfer from the valence to conduction band in the presence of an intense laser field is explored theoretically in semiconductors and dielectrics. Experiments on intense laser driven dielectrics have revealed population transfer to the conduction band that differs from that seen in semiconductors. Our research explores two aspects of ionization in solids. (i) Current ionization theories neglect coupling between valence and conduction band and therewith the dynamic Stark shift. Our single-particle analysis identifies this as a potential reason for the different ionization behaviour. The dynamic Stark shift increases the bandgap with increasing laser intensities thus suppressing ionization to an extent where virtual population oscillation become dominant. The dynamic Stark shift plays a role dominantly in dielectrics which due to the large bandgap can be exposed to significantly higher laser intensities. (ii) In the presence of laser dressed virtual population of the conduction band, elastic collisions potentially transmute virtual into real population resulting in ionization. This process is explored in context of relaxation time approximation.

Full text

Abstract:

Methods of production and optimisation of (F⁺²)H centres in alkali halide crystals have been evaluated with particular reference to these centres in oxygen-doped NaCl crystals. Additionally, a laser cavity has been designed and constructed for use with this material. In order to produce (F⁺²)H centres in NaCl, three main processes are involved: additive colouration, annealing, and a two-stage photoaggregation process. Each of these is discussed and the optimum conditions for each are given. A spectroscopic analysis of the final crystals is then performed with a view to understanding the formation kinetics of the (F⁺²)H centre. This work employs low tempeature emission spectroscopy and polarised luminescence and absorption measurements to evaluate the influence of auxiliary F-band light on the laser operation. Comparisons are drawn between these results involving the excited state transitions of the (F⁺²)H centres and the model obtained by Luty et al. in KC1. The crystals produced in this work have been used in the colour centre cavity designed and to date spikes of laser emission have been obtained.

Abstract:

This thesis covers two areas of laser physics: optical cooling of rare-earth-doped solids by anti-Stokes fluorescence and the generation of pure Laguerre-Gaussian laser modes using a ring-shaped pump beam. A novel laser-based approach to determining local variations in the temperature of transparent samples is developed. This technique is based on monitoring the frequency-shift of the axial modes of a simple, diode-pumped solid-state laser resonator in which the sample is placed. A theoretical resolution of <4.5mK is calculated for a perfectly isolated probe resonator. The technique is validated by comparison to thermocouple measurements of a control sample. The advantages of this diagnostic technique have been demonstrated for the discrimination of local optical cooling from parasitic heating effects. Local cooling of 1.4±0.1K has for the first time been observed in Yb3+:CaF2 using this measurement technique. During the course of the optical cooling experiments regular pulse packets have been observed for sustained self-pulsing in a fibre laser operating significantly above the lasing threshold. This regular pulsing behaviour is observed to break down to irregular pulsing behaviour close to threshold. Extending the resonator length has been demonstrated as a technique for the suppression of self-pulsing. A hollow-core-fibre beam-shaping technique has been developed to selectively generate pure Laguerre-Gaussian laser modes. An astigmatic mode-converter analysis of these modes has proven that an axial mode cannot simultaneously possess both senses of azimuthal phase. The sense of the azimuthal phase has been observed to flip around the peak of the gain spectrum.

Abstract:

The solid particle receiver (SPR) is a direct absorption central receiver that can provide a solar interface with thermal storage for thermochemical hydrogen production processes requiring heat input at temperatures up to 1000 C. In operation, a curtain consisting of ∼690 μm ceramic particles is dropped within the receiver cavity and directly illuminated by concentrated solar energy. The heated particles exit the receiver and may either be stored or sent through a heat exchanger to provide process heat input. The performance of the receiver is dependent on the characteristics of the particle flow including velocity and opacity (optical density). In addition, because the SPR will have an open aperture there is also a possibility that the flow may be disturbed by high ambient winds. Computational models have been and are currently being used to simulate receiver performance at power levels up to several MWt. However, due to the complex two-phase nature of the solid particle flow, such models rely on experimental data both to provide physical input, such as boundary conditions, as well as to provide a point of comparison for model validation. In this paper, we present experimental results from tests performed using a small scale unheated solid particle curtain. These tests focus on the measurement of the flow characteristics of the solid particle curtain as it falls from a near-zero velocity discharge slot to a collection point three meters below. The results include measured values for the variation of velocity, solids volume fraction, curtain width, and curtain opacity along the length of the curtain.
