摘要

利用原位缩合法制备了聚(2-甲氧基-5辛氧基)对苯乙炔(MOPPV)-ZnSe量子点复合材料

通过对复合材料的X射线衍射、透射电子显微镜、扫描电子显微镜、紫外可见吸收光谱等研究

发现聚合物MOPPV与ZnSe量子点以包覆形式有效地复合在一起

复合材料中ZnSe量子点结晶性良好

尺寸约为4 nm;且两者之间发生光诱导电荷转移

复合材料随着退火温度的升高

其吸收光谱范围发生红移。通过对MOPPV-ZnSe复合材料光电性能的研究发现

复合材料光电性能随着退火温度的升高逐渐表现出明显的二极管特性

转换效率出现先增大后减小的趋势

且在160℃时转换效率达到最大为0.3726%。

Abstract

According to high photoelectric conversion performance of quantum dot composite material

we use in situ condensation method to prepare polymer/poly(2-methoxyl-5-octyloxy)-1

4-phenylenevinylene (MOPPV)-ZnSe quantum dot composites. X-ray diffraction

transmission electron microscope

UV-Vis absorption spectroscopy were employed to study their characteristics. The results indicate that MOPPV and ZnSe quantum dots forming a coating or mosaic structure which can be effectively combined

and ZnSe quantum dots keep good crystallinity

each with an average size of 4 nm in the composite

producing the light induced charge transfer phenomenon. The absorption spectra of the composite have a few red-shift with the increasing of the annealing temperature. The study of composite photoelectric performance indicates that it gradually shows obvious characteristic of diode

the power conversion efficiency reaches the maximum of 0.3726% at the temperature of 160℃.
