Method for preparing metal sulfide film and film prepared through method

The disclosure provides a method for preparing a metal sulfide film. The method comprises the steps that an acidic solution comprising metal salt, a sulfur-containing material, a complexing agent anda surfactant is prepared; and a substrate is immersed in the acidic solution, deposition is carried out in a water bath, and the metal sulfide film is formed on the substrate. The invention further provides the metal sulfide film prepared through the method. Through the preparation method disclosed by the invention, the metal sulfide film with high purity and uniform distribution is obtained. 本公开提供一种制备金属硫化物薄膜的方法，包括以下步骤：制备包含金属盐、含硫材料、络合剂、以及表面活性剂的酸性溶液；以及将衬底浸入到所述酸性溶液中并在水浴中进行沉积，从而在所述衬底上形成金属硫化物薄膜。还提供了由该方法获得的金属硫化物薄膜。通过本公开的制备方法，获得了纯度高且薄膜均匀的金属硫化物薄膜。
