Investigation into CdS nanocrystal growth regularities in silicate glass and in the thin films SiO2 at the initial stages of solid solution phase decomposi8tion

Regularities of CdS semiconductor hanocrystal growth in amorphous media (silicate glasses and SiO2 thin films) are investigated. Dependences of crystal mean dimension on the annealing time show that in accordance with the theory of phase decomposition the crystal growth has the successive stages of nuclei formation and diffusion growth. By means of the nuclei mean radius dependences on the annealing temperature are determined the temperatures of CdS solubility in the matrix material. Effect of the annealing atmosphere composition on the growth and optical properties of CdS nanocrystals is shown
