Rod-like nanocrystals of the semiconductor alloy (ZnS)(x)(CuInS(2))(1-x) (ZCIS) have been colloidally prepared by using a one-pot non-injection-based synthetic strategy. The ZCIS nanorods crystallize in the hexagonal wurtzite structure and display preferential growth in the direction of the c axis. The bandgap of these quarternary alloyed nanorods can be conveniently tuned by varying the ratio of ZnS to CuInS(2). A non-linear relationship between the bandgap and the alloy composition is observed. The ZCIS nanorods are found to exhibit promising photocatalytic behaviour in visible-light-driven degradation of Rhodamine B.
棒状纳米晶的半导体合金（ ZnS ）（ X ）（ CuInS （ 2 ））（ 1 - X ）（ ZCIS ）已胶体准备使用一锅非注射的基础上的合成策略。 ZCIS 纳米棒结晶在六方纤锌矿结构和显示在优先生长方向的 C 轴。该带隙的这些四元合金纳米棒可以方便地调整不同的比例 ZnS ，以 CuInS （ 2 ）。非线性关系之间的带隙和合金组成。 ZCIS 纳米棒被发现表现出有前途的光催化行为可见光驱动的罗丹明 B 的降解。
