Abstract: The cadmium carboxylate/silica composite materials(CCSM) were prepared through the combined use of nucleophilic substitution, hydrolysis of siloxane, and condensation of silanol. The CdS nanoparticles of cubic and hexagonal structures were prepared in situ in CCSM by vulcanization. The emission peak of CdS nanoparticles in CCSM belongs to the red fluorescence at 672 nm(one of the three primary colors), suggesting that the CdS/silica composite materials have a potential application as optical devices.
