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%.

Key words: AgInS2@ZnS quantum dots, Core-shell structure, Denatured bovine serum albumin(dBSA), Fluorescence property
