METHOD FOR SYNTHESIZING CADMIUM SULFIDE (CDS) NANOPARTICLES

Abstract

ABSTRACT A method (100) for synthesizing cadmium sulfide (CdS) nanoparticles. Further, the method comprising providing a solution containing cadmium acetate (Cd(OAc)2) as a cadmium source, sodium sulfide (Na2S) as a sulfur source, and thiourea as a stabilizing agent. Further, the method (100) comprising the steps of stirring the solution for a predetermined time to ensure complete dissolution of the components. Further, the method (100) comprising the steps of subjecting the solution to microwave irradiation at a power of approximately 80W for a duration of 5 minutes to facilitate the formation of CdS nanoparticles. Further, the method (100) comprising the steps of isolating the resulting yellow precipitate of CdS nanoparticles. Further, the method (100) comprising the steps of washing the precipitate with ethanol or distilled water and drying it at a temperature of about 55°C for a period of 6 hours. <>
