Abstract
Zinc-boron-silicate and zinc-gallium-phosphate glasses doped with cadmium sulfide-selenide with concentrations ≤ 1.2 wt% were synthesised, and the behaviour of CdSSe microcrystals in the glass matrices under annealing was studied. Phosphate matrix showed better flexibility both for doping procedure and for thermal processing to grow microcrystals. Quantum confinement in II–VI microcrystalline doped glass samples was demonstrated, absorption spectra and structure of the spectra of the phosphate glasses gave evidence of high concentration and good crystalline quality of microcrystals grown in the matrices. An explanation for the observed changes of shape, dimensional dispersion and crystalline structure of the microcrystals is proposed.
