The synthesis of CdS/ZnO and CdS/Pb3O4 composite materials via microwave irradiation

CdS/ZnO, CdS/Pb3O4 composite materials via microwave irradiation were fabricated. The main process was that CdS nanoparticles connected with each other via van der Waals’ action under the induction of microwave irradiation to form CdS cages. CdS cages adsorbed nitrate solutions, which transformed to oxides by calcination and formed CdS/ZnO and CdS/Pb3O4 composite materials. Both CdS and ZnO photoluminescence emissions were observed simultaneously.
