摘要: 用CdO通过高温化学方法制备了具有高发光特性的CdSe胶体纳米晶.通过改变配体十六烷基胺在反应体系中的含量,合成了3种不同粒径的CdSe纳米晶.利用TEM、XRD和光谱等手段对合成出来的CdSe纳米晶的形貌结构和发光特性进行了表征.结果表明,随着十六烷基胺在反应体系中量的增多,CdSe纳米晶的粒径增大.通过调整十六烷基胺在反应体系中的量可以方便地控制纳米晶的尺寸.

关键词: CdO, 高温化学反应, 十六烷基胺, CdSe纳米晶

Abstract: CdSe colloid nanocrystals with a High luminescence quality were synthesized by the reaction of CdO and Se precursors at a high temperature. In this experiment,three kinds of sizes of CdSe nanocrystals were obtained by changing the amount of hexadecyl amine in the system. With TEM,XRD and fluorescence emission spectra,we characterized the morphology,structure and optical quality. The results indicate that hexadecyl amine has so great effect on the size of nanocrystals that the size of CdSe nanocrystal increases with increasing the amount of hexadecyl amine

Key words: CdO, High temperature reaction, Hexadecyl amine, CdSen anocrystals
