摘要
在无水甲醇介质中,以CdCl2为镉源,Na2S为硫源,3-巯基丙基三甲氧基硅烷(MPS)为稳定剂,一步合成了CdS/SiO2核/壳结构的纳米颗粒.以扫描探针显微镜对其形貌进行表征,并研究了掺杂不同金属离子对其荧光光谱的影响.
A novel one-step preparation method for core-shell CdS/SiO2 nanoparticles was proposed using 3-mercaptopropyl-trimethoxysilane （MPS） as stabilizing agent in MeOH ,in which CdCl2 · 2. 5H2O and Na2S · 9H2O were used as the source of Cd and S,respectively . The morphology of products was characterized by scanning probe microscope ,and the influence of Zn and Cu on the fluorescence property was discussed.
