以乙酰丙酮铜(Cu(AcAc)2)、乙酸锌(Zn(CH3COO)2·2H2O)、氯化亚锡(SnCl2·2H2O)、升华硫(S粉)和十二硫醇为原料,用热注射法合成了Cu2ZnSnS4(CZTS)纳米晶.再将Cu2ZnSnS4纳米晶制成胶体墨水,用旋涂法制备出Cu2ZnSnS4薄膜.用X射线衍射(XRD)仪、拉曼光谱(RS)仪、透射电镜(TEM)、扫描电镜(SEM)、X射线能量色散谱仪(EDS)和紫外-可见光谱(UV-Vis)分光光度计对CZTS纳米晶及薄膜的晶体结构、微观形貌、化学组成及光学性能进行表征,研究了注射温度对纳米晶结构、形貌、晶粒大小以及化学组成的影响以及热处理时间对Cu2ZnSnS4薄膜结构、形貌、化学组成和光学性能的影响.结果表明,在注射温度为180℃时合成的CZTS纳米晶为锌黄锡矿结构,平均粒径为18nm.在500℃热处理2h所制备出的薄膜,在可见光范围内其吸收系数高达104 cm-1,禁带宽度为1.45 eV.
