摘　　要：在水相中成功地合成了谷胱甘肽包裹的CdTe纳米粒子,选择了荧光峰为554nm左右的CdTe纳米粒子作为CdTe-H2O2化学发光体系中的发光体.研究了H2O2浓度、反应介质、CdTe粒径、浓度等碲化镉量子点体系的化学发光行为的研究,并试验了不同包裹剂下的CdTe化学发光行为.在最佳的实验条件下,研究了Cu2+、Pb2+等几种金属离子的对CdTe-H2O2化学发光体系的影响,建立了金属离子检测的工作曲线.Glutathione（GSH）-capped CdTe quantum dots（QDs） were synthesized in aqueous medium,and the CdTe QDs emitted at 554 nm was selected as the luminophor in CdTe-H2O2 chemiluminescence system.The reaction conditions,including oxidants,reaction medium,size of CdTes and concentration of CdTes,were investigated.The chemiluminescence behavior of the system was studied when the CdTes capped by different stabilizers.Under the optimized conditions,the linear ranges for different ions （such as Cu2＋,Pb2＋） were obtained.ChinaAbstract：Glutathione（GSH）-capped CdTe quantum dots（QDs） were synthesized in aqueous medium,and the CdTe QDs emitted at 554 nm was selected as the luminophor in CdTe-H2O2 chemiluminescence system.The reaction conditions,including oxidants,reaction medium,size of CdTes and concentration of CdTes,were investigated.The chemiluminescence behavior of the system was studied when the CdTes capped by different stabilizers.Under the optimized conditions,the linear ranges for different ions （such as Cu2＋,Pb2＋） were obtained.
