摘　　要：用再沉淀法制备了苝纳米溶胶并对其荧光性能进行了研究,实验发现其荧光激发光谱和发射光谱分别为400nm和565nm.当该体系中加入少量表面活性剂时,体系的荧光强度(λem=565nm)随着表面活性剂浓度的增加而增加,但是当表面活性剂浓度过大时体系的荧光强度随着表面活性剂浓度的增加而降低.本文对此种现象进行了机理讨论.This paper reports on the preparation of perylene colloids by using the reprecipitation method and studies the properties of colloids fluorescence.The experiments conducted showed that the fluorescence excitation and emission were measured at 400 nm and 565 nm respectively.The fluorescence intensity(λem=565nm) was significantly increased by increasing surfactants concentration in a lower region.However,the fluorescence intensity of colloids decreased when the concentration of surfactants was too high.This paper discusses the physical mechanism of the phenomenon.
