Embodiment 1
[0034] (1) Measure absolute ethanol and deionized water in a beaker in sequence to obtain 30 mL of ethanol aqueous solution, wherein the volume ratio of absolute ethanol and deionized water is 1:0.5.
[0035](2) Weigh 0.1233g, 0.3056g and 0.2104g of cadmium nitrate, indium nitrate hydrate and thioacetamide respectively, and add them in sequence to the ethanol aqueous solution obtained in step (1). Stir for 10 minutes and sonicate for 5 minutes to form a yellowish solution. Transfer the obtained solution to a polytetrafluoroethylene-lined autoclave for 24 hours at 180 ° C. After the reactor is cooled to room temperature, the solid in the solution is After centrifugation and ultrasonic cleaning with ethanol and water for three times, dry at 80°C for 12 hours to synthesize CdIn 2 S 4 The nano cube is 0.187g, and the side length of the cube is 50-100nm.
