抄録

We have prepared ZnS–CdS alloy (Zn_1−xCd_xS) quantum dots (QDs) using chemical synthetic methods and investigated size-selective photoetching effects on the size distribution. The preparation of Zn_1−xCd_xS QDs with an alloy composition from x=0 to x=1 is successful using either of the following two methods: a reverse-micelle method using AOT/heptane micellar solutions, and a standard colloidal method in aqueous polyvinyl pyrrolidone solution. Reduction of the size distribution of the colloidal alloy QD to ∼5% was achieved by a size-selective photoetching process. The present results indicate the potential of preparing Zn_1−xCd_xS QDs with a narrow size distribution.
