摘要
以聚酰胺－胺（PAMAM）树形分子为模板，原位合成CdS，AMAM树形分子纳米复合材料，探索不同负载比对其性能的影响及量子点表面的功能性。通过荧光光谱技术，分析Cu^2＋和Mn^2＋重金属离子对其光致发光性能的影响，利用光学性质变化、材料分析稳定度考察其反应机制。
Using Poly with different generati （amido amine） PAMAM as templates, CdS quantum dots/PAMAM dendrimers on were in situ synthesized. The surface functionality of CdS quantum dot was investigated. The influence of heavy metal ion Cu and Mn on the CdS quantum dots/PAMAM photoluminescence were investigated. And the reaction mechanism was investigated by optical change and material stability.
