CdS/SiO2纳米复合材料的合成及光学性能
Synthesis and Optic Properties of Sulfide/Silica Nanocomposite Material
摘要
Abstract
In conventional methods to preparation silica, it is inevitably to use the acid or basic catalysts, which have a destructive effect on molecules or particles that are sensitive to pH. These methods have signifi-cant limitations in the preparation of the silica composites materials. Therefore, it is still a great challenge to find a mild way to synthesize silica. In this paper, we used synthesized of alanine cadmium as a precursor of the nanoparcitles, taking advantage of the amine group in the alanine cadmium molecule as catalyst to catalyze siloxane hydrolysis and condensation without added acid or basic catalysts, meanwhile, the alanine cadmium was introduced to the silica. Then the CdS nanoparcitles were prepared by in situ the way of vulcanization. The characterization of the material through Fourier transform infrared spectroscopy, proton nuclear magnetic resonance, ultraviolet-visible spectrum, fluorescence microscopy and transmission electron microscopy shows that the nanocomposites material with the CdS particle uniformly distribution in silica are synthesized. The material has excellent fluorescence properties.关键词
