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.
