Transparent glass with composition 65LiNbO3-35SiO2 was fabricated via the conventional melt-quenching technique. Glass-ceramics containing nanoscale (less than 100 nm) rhombohedral lithium niobate crystals were successfully produced by annealing the respective glass at various temperatures (600, 650 700 and 975 °C) for 1 h. The result of optical transmission spectra shows that the quenched sample is optically transparent. Transparent samples should possess crystals << 200 nm and have a narrow distribution of crystal sizes.

This paper reports on successful experiments in growing beta-gallium oxide crystals using the Czochralski method. The influence of growth atmosphere composition on crystal quality of the material was studied. It is shown that to obtain high quality optically transparent crystals it is necessary to have about 5 vol.% oxygen in the growth atmosphere. X-ray structural analysis and investigation of optical transmission spectra of grown crystals are carried out.

Principal Possibility

Principal possibility of the using of chalcogenide glasses (on the example of Ge18As18Se64) as active media for temperature sensors is considered in this work. Differential scanning calorimetry testing of the investigated glasses shown that 2 years of natural storage does not lead to the drift of their DSC-parameters (glass transition temperature and endothermic peak area). Investigation of the temperature dependence of optical transmission spectra shows the linear character of optical band-gap changes with a temperature. Temperature sensitivity index β for Ge18As18Se64 is estimated to be equal to the ~1.2·10-3 eV/°C.

Optical Transmission Spectra

AbstractOptical transmission spectra are collected in the ferromagnetic state of GdN at various temperatures. The temperature dependent extinction coefficient extracted from the transmission measurements show that the conduction and valence band states are spin polarized. The results confirm the LSDA+U estimates of the energy gap associated with the majority/minority-spins and also the magnitude of the spin splitting.
