摘要

CdSe量子棒是一种具有良好光学特性的半导体纳米材料，不同长径比的量子棒可应用于光电材料及器件制备。采用高温油相合成法制备CdSe量子棒，在只改变前体反应时间的前提下，探究其对于CdSe量子棒长径比的变化机理并对其光学特性进行对比分析。实验结果表明CdSe量子棒随着反应时间的增长粒径增大并且发射峰的峰位产生了红移的现象。通过透射电子显微镜表征后发现量子棒随着前体反应时间的增加长度逐渐变长，长径比逐渐变大。因此可以用该方法可以控制量子棒的生长。

Abstract

Cadmium selenide(CdSe) quantum rods are semiconductor nanomaterials with good optical properties. Quantum rods with different aspect ratios can be applied to optoelectronic materials and device fabrication. The CdSe quantum rods were prepared by high temperature oil phase synthesis. Under the premise of changing the reaction time of the precursors

the change mechanism of the length-diameter ratio of CdSe quantum rods was investigated and the optical properties were compared. The results show that the particle size of CdSe quantum rod increases with the increase of reaction time and the peak position of the emission peak produces a red shift phenomenon. After characterization by transmission electron microscopy

it was found that the quantum rod gradually became longer as the reaction time of the precursor increased

and the aspect ratio gradually became larger. Therefore

the growth of the quantum rod can be controlled by this method.
