| 摘 要： | 以巯基丙酸(RSH)为稳定剂，采用湿化学法合成了功能性CdSe纳米晶，用XRD、TEM表征其粒度和形貌，用UV-Vis监测成核及成膜过程。结果表明：制得的CdSe近似呈球形，平均粒径为48 nm。利用静电自组装法层层组装成CdSe-PDDA复合膜，荧光测试表明：所得CdSe纳米晶自组装复合膜(CdSe-PDDA)的荧光强度随着组装层数的增加而呈线性增强，该复合膜在582 nm附近有黄绿色荧光发射。

| Abstract: | CdSe, a functionalized nanocrystal was synthesized with mercaptopropionic acid (RSH) as a stabilizer by a wet chemical method. The nanocrystals were characterized by XRD and TEM. The nucleation process and film forming process were observed by UV-Vis absorption spectra. The functionalized CdSe nanocrystals were in globular shape and the average diameter was 48 nm. The luminous performance of CdSe-PDDA complex pellicle synthesized by static self-assembly was studied by fluorescence emission spectra. The results show that the luminous performance of complex pellicle, compared with CdSe nanocrystals with a single component, change in a certain degree. The composite membrane has a yellowish green fluorescence-emission at 582 nm. |
