我们展示了一种无膦的方法来合成重Co2+和Fe2+掺杂的Cu2SnSe3纳米晶体（NC）凭借烷基硫醇辅助Se粉末溶解在有机溶剂中。在AM1.5光照下，所合成的NC表现出有希望的光电流增加。由于目前的方法是简单和方便的，它持有的承诺，促进光伏器件的进展，从铜基纳米碳。
We demonstrate a phosphine-free method to synthesize heavy Co2+- and Fe2+-doped Cu2SnSe3 nanocrystals (NCs) by virtue of alkylthiol-assistant Se powder dissolution in organic solvents. The as-synthesized NCs exhibit a promising increase in photocurrent under AM1.5 illumination. Since the current method is simple and convenient it holds promise for facilitating the progress in photovoltaic devices from Cu-based NCs.
