溶剂热法合成CdSxSe1-x棒状纳米材料
Solvothermal Synthesis of CdSxSe1-x Nanorods
【摘要】 以乙二胺为溶剂,制备了直径为10￣20nm、长度100￣150nm的棒状CdSxSe1-x纳米晶体,并对其形成过程及机理进行了探讨。研究发现CdSxSe1-x纳米晶体在120℃下就可形成且纳米棒的形貌不受温度及反应物配比的影响。紫外-可见光谱表明得到的CdSxSe1-x纳米晶体的光学性质可通过简单改变反应物中S与Se的配比进行调控。
【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.
