The millimetersized tubular crystal selenium was first prepared. By studying the process of treating selenium in ethylenediamine, we proposed the mechanism of the preparation of selenides under solvothermal condition. The selenides came into being from the reaction of metal ions with Se〓, which was obtained by the amine attacking selenium. Moreover, a new precursor to prepare nanocrystalline selenides at room temperature was obtained. From this precursor, we have prepared nanocrystalline silver selenides, copper selenides, lead selenides and cadmium selenides nanorods.
