Analysis of structural defects in the CdSexS1 – x nanocrystals

Resumo

Spectral dependence of the absorption coefficient of the CdSe_xS_{1 – x} nanocrystals in silicate glass with different perfections of crystalline lattice is experimentally studied. A dependence of the concentration of defects on the time of thermal processing is obtained. It is demonstrated that the defect elimination results from thermal activation process.
