Solvothermal Synthesis of CdS_xSe_(1-x) Nanorods

Qiu Hua

Abstract

CdSxSe1-x (0≤x≤1) nanorods with diameter of 10~20 nm and length up to 150 nm were successfully synthesized via a solvothermal route. CdSxSe1-x nanorods could be obtained at a temperature as low as 120 ℃ and the size distribution of the nanorods did not change with temperature and composition. The 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.
