采用简单的超声-微波溶剂热法合成了纤锌矿Cu 2 ZnSnS 4（CZTS）六棱柱。采用XRD、FESEM、EDS、TEM、拉曼光谱和紫外-可见光谱对产物进行了表征。六棱柱宽0.5-2 μ m，长5-12 μ m。PVP在CZTS六棱柱的形成过程中起到了重要的作用。此外，超声辅助微波过程有助于合成纤锌矿而不是锌黄锡矿相CZTS。提出了一种形核-溶解-再结晶机制来解释CZTS六方棱柱的生长。(C)2015 Elsevier Inc. All rights reserved.
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.
