摘要
水相合成CdSe量子点时掺杂Pb2+一步合成了CdPbSe三元量子点。控制不同的反应时间得到了不同粒径的量子点,这些量子点都具有良好的荧光特性,且荧光发射随合成时间的延长有明显的红移。
Ternary CdPbSe quantum dots with high fluorescence efficiency are composed byintroducing Pb2+ in synthesis process of CdSe NCs in aqueous medium.It's found that quantum dots withdifferent particle diameters are obtained with different reaction time.What's more,these quantum dotspossess good fluorescence characteristics and their fluorescence emission makes distinct red shifts with theprolonged reaction time.
