Abstract

CdSxSe1−x (0 ≤ x ≤ 1) nanorods with diameter of 10–20 nm and length up to 100–150 nm were successfully synthesized via a solvothermal route. It was found that the CdSxSe1−x nanorods could be obtained at a temperature as low as 120 °C and the size distribution of the nanorods did not change with temperature and composition. A thin layer of CdS was detected beside the CdSxSe1−x products and proposed to act as crystal seeds in the incorporating process of CdSxSe1−x, thus decreasing the reaction temperature effectively. The exploration of ultraviolet–visible (UV–vis) absorption properties of the CdSxSe1−x samples confirmed that the band gaps of the CdSxSe1−x nanocrystals could be easily tuned via the control of composition, which may indicate its wide application in many fields.
