Highly homogeneous and luminescent CdSe colloidal nanocrystals in the less common zinc blende crystal structure have been obtained at high temperature in a noncoordinating organic solvent. The key parameter appears to be the addition of a phosphonic acid to the trioctylphosphine-selenium complex before its injection into the hot cadmium mixture, while the role of temperature is less relevant. Compared to standard (wurtzite) colloidal CdSe preparations, we find that the growth rate is considerably reduced, and the energy gap between the first two absorption bands becomes larger.
在一种非配位有机溶剂中，于高温下制备出了具有高度均一性且发光的、呈不太常见的闪锌矿晶体结构的CdSe胶体纳米晶体。关键参数似乎是在将三辛基膦 - 硒络合物注入热的镉混合物之前向其中添加膦酸，而温度的作用相对较小。与标准（纤锌矿）胶体CdSe制剂相比，我们发现生长速率显著降低，并且前两个吸收带之间的能隙变大。
