摘要:
Wurtzite Cu2ZnSnS4 (CZTS) hexagonal prisms were synthesized by a simple ultrasound-microwave solvothermal method. The product was characterized by XRD, FESEM, EDS, TEM, Raman and UV-vis spectrometer. The hexagonal prisms were 0.5-2 mu m wide and 5-12 mu m long. The PVP played an important role in the formation of the CZTS hexagonal prisms. In addition, the ultrasound-assisted microwave process was helpful for synthesis of wurtzite rather than kesterite phase CZTS. A nucleation-dissolution-recrystallization mechanism was also proposed to explain the growth of the CZTS hexagonal prisms. (C) 2015 Elsevier Inc. All rights reserved.
