Abstract
Zinc-boron-silicate glass doped with cadmium sulfide-selenide was synthesized, and arising and growth of Cd-S-Se microcrystals in the glass matrix under annealing was studied. The annealing dependant shift of absorption edge of the glass samples was demonstrated. Transmission electron microscopy proved that quantum confinement effect was an origin of the shifts. Growth of the microcrystals was followed by increase of their dispersion. Also the growth led to transformation of structure of the microcrystals from cubical to hexagonal. Cesium-potassium ion exchange in the SDG was applied to optical waveguides formation. Differences of the alkaline ion profiles in the glass samples annealed differently were observed.
