中文摘要：

本文在合成水溶性巯基乙酸修饰的CdTe量子点的基础上,研究了CdTe量子点与罗丹明6G之间的荧光共振能量转移。实验结果表明：构建的CdTe量子点（供体）-罗丹明6G（受体）荧光共振能量转移体系在磷酸盐缓冲溶液中有较好的转移效果。当磷酸缓冲溶液pH值为7.4,NaCl浓度为1.0mol/L时,构建的CdTe量子点-罗丹明6G荧光共振能量转移效率为62%;罗丹明6G既能与CdTe量子点表面的修饰试剂作用,也能与CdTe量子点本身直接作用,其作用力为静电相互作用和配位作用。

英文摘要：

CdTe quantum dots（QDs） were synthesized in aqueous medium by employing thioglycolic acid as a stabilizer.The fluorescence resonance energy transfer（FRET） between CdTe QDs and rhodamine 6G（Rh 6G） was investigated.The results showed that the energy transfer efficiency was 62% at pH=7.4 in 1.0 mol/L NaCl.Rh 6G molecules interacted not only with thioglycolic acid but also with the surface of CdTe QDs directly.The forces of the interaction were electrostatic interaction and coordinate interaction.
