采用化学合成方法制备了ZnS-CDS合金(Zn1-xCdxS)量子点，研究了尺寸选择性光刻对量子点尺寸分布的影响。用AOT/正庚烷胶束溶液反胶束法和聚乙烯吡咯烷酮水溶液胶体法成功地制备了合金成分从x=0到x=1的Zn1-xCdxS量子点。通过尺寸选择光刻工艺，将胶体合金QD的尺寸分布减小到∼的5%。研究结果表明，制备尺寸分布较窄的Zn1-xCdxS量子点是有潜力的。
We have prepared ZnS–CdS alloy (Zn1-xCdxS) quantum dots (QDs) using chemical synthetic methods and investigated size-selective photoetching effects on the size distribution. The preparation of Zn1-xCdxS 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 Zn1-xCdxS QDs with a narrow size distribution.
