报道了一种新的合成具有尺寸依赖光学性质的胶体ZnSe纳米晶体的方法。在非配位溶剂（十八烷）中，通过硬脂酸锌与溶解在三辛基膦中的硒直接反应制备了ZnSe量子点，即不使用焦性试剂。所得纳米晶体的光致发光可以在390-440光谱范围内调谐，发射线宽度恒定，约为15 nm。(C) 2003 Elsevier B.V.版权所有
A new synthesis method of colloidal ZnSe nanocrystals exhibiting size-dependent optical properties is reported. The ZnSe quantum dots are prepared in a non-coordinating solvent (octadecane) via direct reaction of zinc stearate with selenium dissolved in trioctylphosphine, i.e., without the use of pyrophoric reagents. The photoluminescence of the resulting nanocrystals can be tuned in the spectral range 390-440 run with constant emission linewidths of the order of 15 nm. (C) 2003 Elsevier B.V. All rights reserved.
