摘要:

合成了一种新型核壳结构的AgInS2@ZnS量子点并研究了其荧光性能. AgInS2@ZnS的合成包括以变性牛血清白蛋白(dBSA)为稳定剂水相法构建AgInS2核以及形成ZnS壳两部分. 考察了配方和工艺条件对该量子点荧光性能的影响, 并采用X射线粉末衍射(XRD)等手段对制备的纳米粒子进行了表征. 结果表明, AgInS2@ZnS是一种核壳结构的纳米物质, 其粒径介于5~7 nm之间, 荧光量子产率达35.3%.

Abstract:

A novel water-soluble AgInS2@ZnS quantum dots(AgInS2@ZnS QDs) in aqueous solution was synthesized. The preparation of AgInS2@ZnS QDs includes the formation of AgInS2 core with denatured bovine serum albumin(dBSA) as the stabilizer and the coating of ZnS on the surface of the core. The effects of ingredient and conditions on the fluorescence of AgInS2@ZnS QDs were investigated. The characterizations of AgInS2@ZnS QDs were studied via X-ray diffraction pattern(XRD), scanning tunneling microscopy(STM) and so on. The results show that AgInS2@ZnS QDs are a core-shell nano-materials, the size range of the resultant particles is 5-7 nm, and the quantum yield is determined to be 35.3%.
