摘要：

Wurtzite and kesterite structured CZTS nanoparticles were synthesized by a solvothermal method using C2H5NS, CS(NH2)(2) and Na2S2O3 center dot 5H(2)O, respectively. Time dependent XRD, EDS and Raman spectra measurements indicated that the different reaction processes or conditions had a great effect on the structural properties and phase purities of CZTS nanoparticles. XPS spectra confirmed their valence states. CZTS were mainly sphere-like and sheet-like particles when Na2S2O3 center dot 5H(2)O and CS(NH2)(2) were used as the sulfur precursors, respectively. The band gaps of as-synthesized CZTS nanoparticles were about 1.48-1.51 eV, which were very suitable for photovoltaic applications. (C) 2014 Elsevier Ltd. All rights reserved.
