8-羟基喹啉修饰玻璃基质中CdS纳米粒子的制备及性质

Study on the Preparation and Properties of CdS Nanoparticles Dispersed in SiO_2 and Modified with 8-Hydroxyquinoline

采用溶胶凝胶法制备了8羟基喹啉修饰的CdS-SiO2复合材料并用多种谱学方法进行了表征,比较了修饰前后的荧光发射光谱.发现没有修饰的CdS-SiO2复合材料只产生激子荧光发射峰,用8羟基喹啉修饰后,激子荧光发射峰和表面态荧光发射峰都能产生,这为非线性光学玻璃的改性提供了一个新的思路.

CdS-SiO_2 nanocomposites modified by 8-hydroxyquinoline with are prepared through sol-gel method. Their preparation and Properties are studied by XRD、TG-DTA、FT-IR. The results show that the excitionic luminescence is decreased and the trapped luminescence is increased.
