摘要:
以乙酸锡(Sn(OAc)4)、CuCl2·2H2O和ZnCl2为金属前驱体原料,正十二硫醇(1-DDT)作为硫源,油胺(OAm)作为溶剂,采用热注入法合成铜锌锡硫(Cu2ZnSnS4,CZTS)纳米晶体,考察反应温度、反应时间、溶剂和离子掺杂对晶体形貌、尺寸的影响。将产物用无水乙醇洗涤后分散到正己烷中制成胶体溶液,采用X线衍射仪(XRD)、透射电子显微镜(TEM)、紫外-可见近红外光谱仪(UV-Vis)、拉曼光谱仪和能谱仪(EDS)对合成的纳米晶体进行表征。结果表明:米粒状产物属于纤锌矿Cu2ZnSnS4,粒子长度为10~30 nm,它对应的禁带宽度为1.52 eV。
Abstract:
Cu2ZnSnS4(CZTS)nanocrystals were synthesized by hot-injection method using copper chloride dihydrate,zinc acetate,and tin acetate as metal precursor materials,n-dodecyl alcohol(1-DDT)as S resources,and oleylamine(OAm)as the solvent.The effects of temperature,time,solvent and ion doping on crystal morphology and size were investigated.The product was washed with absolute ethanol and dispersed in n-hexane to prepare a colloidal solution.The products were characterized by X-ray diffraction(XRD),transmission electron microscopy(TEM),ultraviolet-visible spectrophotometer(UV-Vis)Raman spectrophotometer,and energy dispersive spectroscopy(EDS).Results showed that the rice-like particles were wurtzite CZTS,the length of rice-like particles was 10-30 nm,and the corresponding band gap of products was 1.52 eV.
