Cd2+前体反应时间对CdSe量子棒长径比的调控及其光学特性研究
Regulation of Cd2+precursor reaction time on aspect ratio of CdSe quantum rod and its optical properties
摘要
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.关键词
