摘要：

Small-sized CdS crystals were prepared in SiO2 and Na2O-ZrO2-SiO2 glasses by the sol-gel process and the oxidation of CdS crystals was investigated. Gels synthesized by the hydrolysis of a complex of metal alkoxides and Cd(CH3COO)2. 2H2O were heated at 500-degrees-C and allowed to react with H2S gas to form hexagonal CdS microcrystals. CdS crystals in SiO2 glass were sensitive to oxidation by heating in air. CdS crystals in Na2O-ZrO2-SiO2 glass were smaller than those in SiO2 glass and stable against oxidation in air. The effect of glass composition on the oxidation of CdS crystals was apparent in the emission spectra of glasses soaked in methyl viologen.
