近年来纳米尺寸半导体超微粒的合成和光学性质研究引起了人们广泛的关注,并迅速发展成非常活跃的研究领域.各种半导体(如Ⅱ～Ⅵ族的CdS,ZnS,Ⅲ～Ⅴ族的GaP,GaAs等)超微粒被制备在聚合物、有机溶液和玻璃等介质中.伴随着微粒尺寸的减小,显著的量子尺寸效应和由之引起的各种光学性质变化在这些材料中得到了系统的研究,量子尺寸效应和各种非线性响应增强机制的理论和实验工作也日趋完善.但是,这些工作仅限于研究半 In recent years, the research on the synthesis and optical properties of nano-size semiconductor ultra-fine particles has aroused widespread concern and rapidly developed into a very active field of research.A variety of semiconductors (such as Ⅱ ~ Ⅵ group of CdS, ZnS, Ⅲ ~ Ⅴ GaP , GaAs, etc.) Ultrafine particles are prepared in media such as polymers, organic solutions, glass, etc. With the reduction in particle size, significant quantum size effects and the resulting changes in optical properties are obtained in these materials Research and quantum size effects and a variety of non-linear response enhancement mechanisms are also increasingly perfect theoretical and experimental work However, these studies are limited to half of the study
