Autor: Yu. Blagidze, G. Mshvelidze, O. Gogolin, R. Janelidze, E. Tsitsishvili
Publikováno v: Solid State Ionics. 260:90-93
We report measurements of dynamic (a.c.) electrical conductivity in borosilicate glasses doped with cadmium sulfoselenide and copper and silver iodides in a wide temperature range below the glass transition temperature T g and at different frequencie

Publikováno v: Journal of Luminescence. :451-454
The absorption spectra of CuBr, CuCl, CuI, and AgI nanocrystals (NC) embedded in a glass matrix have been investigated in a wide temperature range between T =6 and 860 K. The change of the absorption in the vicinity of the exciton resonance for CuBr

Publikováno v: Journal of Luminescence. :414-416
The results on the selective photoluminescence (PL), photoluminescence excitation (PLE) and the degree of linear polarization (DLP) for the PL spectrum in AgI nanocrystals (NC) embedded in a glass host matrix are presented. The measurements indicate

Temperature dependence of exciton peak energies in CuI quantum dots
Autor: Claus F. Klingshirn, A. Hepting, Michael Schmidt, E. Tsitsishvili, O. V. Gogolin, G. Mshvelidze
Publikováno v: Solid State Communications. 122:511-513
The temperature dependence of exciton peak energies in large CuI quantum dots embedded in a glass matrix has been measured. The gap shrinkage effect for both cubic and hexagonal CuI phases was observed. The temperature coefficients of the energy gaps

Stimulated emission from a needle-shaped neodymium glass laser
Autor: M. I. Dzhibladze, G. G. Mshvelidze, L. E. Lazarev
Publikováno v: Soviet Journal of Quantum Electronics. 14:89-91
An investigation was made of the kinetics of lasing in neodymium-doped silicate glasses in the form of thin needle-shaped rods with diameters ~ 1 mm and 30–40 cm long. A similarity with fiber lasers was observed. The output radiation included regul
