Abstract
The invention discloses a method for preparing cadmium sulfide nano-film by using dimetbylformamide. The method comprises the following steps: treating conductive glass and graphite electrode through ultrasonic cleaning by using distilled water and alcohol, drying for standby, pouring 0.0001-0.00015mol of cadmium chloride and 0.0005-0.00065mol of sulfur source in a beaker, adding 10-15ml of pure dimetbylformamide to stir, then placing the beaker in a water bath kettle to heat to 50-90 DEG C, using graphite electrode as anode and conductive glass as cathode to electrodeposit under the constant pressure of 2-8V for 2-6 min and obtaining the cadmium sulfide nano-film, wherein the sulfur source is one of source and thioacetamide. The synthesis method of the invention has simple equipment, convenient operation, fast synthesis and controllable film thickness; in addition, the prepared cadmium sulfide nano-film has uniform color and smooth surface, the film is firm and hard to drop off, and the film has a certain electrical/optical characteristic.
