| 摘 要： | 采用荧光发射法研究了不同Cd2+与树形分子的摩尔比(负载比)条件下硫化镉(CdS)/聚酰胺-胺(RAMAM)树形分子纳米复合材料(NCs)水溶液的荧光性能,并探索了其荧光产生的机理.结果表明:在波长330 nm光的激发下,CdS/G4.0-NH2PAMAM NCs的荧光发射光谱中出现了2个峰,一个是PAMAM树形分子的...

| Abstract: | The photoluminescence property of CdS/PAMAM nanocomposites in water at different ratio of Cd2+to PAMAM(r)was studied by fluorescence emission spectrum,and the according mechanism was explored.The results indicate that in the irra-diation of UV light at the wavelength of 330nm,two peaks were shown in the fluorescence emission spectrum of CdS/PAMAMnanocomposites.One peak was attributed to PAMAM dendrimers,and the another came from CdS QDs.The strength of thefrontier fluorescence emission peak became weaker an... |
