制备了尺寸可调、光致发光强度比和发光范围可控的Cu，Mn:ZnSe量子点。实验条件的研究证实，Cu，Mn:ZnSe量子点的大小受溶液pH、注入速度和反应温度的影响。一般来说，高pH、低注射速度和高反应温度是制备大量子点的最佳条件。在此基础上，合成了不同尺寸的Cu，Mn:ZnSe量子点。通过控制实验条件和Mn:Cu的投料摩尔比，设计了白色发射Cu，Mn:ZnSe量子点。
Cu,Mn:ZnSe quantum dots (QDs) of tunable size, controllable photoluminescence (PL) intensity ratio and PL range were prepared. A study of the experimental conditions confirmed that the size of Cu,Mn:ZnSe QDs is affected by the pH of the solution, the speed at which the Zn solution is injected and the reaction temperature. In general, high pH, low injection speed and high reaction temperature are optimal for preparing large QDs. Based on this knowledge, different sizes of Cu,Mn:ZnSe QDs were synthesized. Moreover, white emission Cu,Mn:ZnSe QDs were designed by controlling the experimental conditions and the feeding mole ratio of Mn:Cu.
