The first colloidal nanoparticle synthesis of the copper selenophosphate Cu3 PSe4 , a promising new material for photovoltaics, is reported. Because the formation of binary copper selenide impurities seemed to form more readily, two approaches were developed to install phosphorus bonds directly: 1) the synthesis of molecular P4 Se3 and subsequent reaction with a copper precursor, (P-Se)+Cu, and 2) the synthesis of copper phosphide, Cu3 P, nanoparticles and subsequent reaction with a selenium precursor, (Cu-P)+Se. The isolation and purification of Cu3 P nanoparticles and subsequent selenization yielded phase-pure Cu3 PSe4 . Solvent effects and Se precursor reactivities were elucidated and were key to understanding the final reaction conditions.

硒化磷酸铜Cu3 PSe4的胶体纳米颗粒合成的直接路线。

据报道，硒磷酸盐铜Cu 3 PSe 4的首次胶体纳米颗粒合成是一种有前途的光伏新材料。由于似乎更容易形成二元硒化铜杂质，因此开发了两种直接安装磷键的方法：1）分子P4 Se3的合成以及随后与铜前体（P-Se）+ Cu的反应，以及2 ）磷化铜，Cu3P，纳米粒子的合成以及随后与硒前体（Cu-P）+ Se的反应分离纯化Cu3 P纳米粒子，然后硒化，得到纯相Cu3 PSe4。阐明了溶剂效应和Se前驱体的反应性，这对于理解最终反应条件至关重要。
