| description | The invention discloses a preparation method of germanium diselenide, and belongs to the technical field of compound preparation. The preparation method of germanium diselenide comprises the following steps: mixing and ball-milling sieved germanium powder and sieved selenium powder, carrying out heating reaction in an inert gas environment, then removing attachments on the surface of a heating reaction product, crushing, and carrying out heat preservation reaction on the crushed product in the inert gas environment to obtain the germanium diselenide. Therefore, golden yellow crystalline germanium diselenide can be obtained; the obtained germanium diselenide is high in purity and free of segregation, and meanwhile, the loss of the obtained germanium diselenide is small, namely, the yield is high. Moreover, the preparation method provided by the invention is simple to operate, does not need special equipment, and is beneficial to actual production and application.
