Abstract：
 The present invention discloses process of preparing monodisperse nanometer semiconductor selenide particle. The present invention prepares the monodisperse nanometer semiconductor selenide particle through reaction between metal ionic solution and selenium source inside the mixture system comprising alkali metal oxide, fatty acid and organic polar solvent. The selenium source is mixture system comprising selenide and reductant or metal selenium powder. The process of the present invention is simple, safe, low in cost, low in environmental pollution, and suitable for synthesis of several kinds of nanometer semiconductor selenide particle. The prepared nanometer semiconductor selenide particle may be applied widely in biological marker, analysis, solar cell and other fields.
