The invention discloses a method for regulating and controlling filming speed of scheelite film, belonging to the technical field of oxide film preparation. In the invention, the original system is adopted, oxidant is added at cathode or in cathode electrolyte, and type and concentration of oxidant is changed to control the reaction speed of anode tungsten or molybdenum to form tungstate or molybdate film layer. The method is carried out at room temperature without heat treatment, thus avoiding flaws caused in heat treatment crystallization process, quickly synthesizing tungstate and molybdate polycrystal films with good luminous performance. The invention dispenses with heating procedure and external electrochemical equipment, and has the characteristic of zero energy consumption.
