摘　　要：以Ag2S作为催化剂,二丁基二硫代氨基甲酸锌钴([(C_(4)H_(9))2NCS_(2)]_(2)Zn_(1-x)Co_(x))为前驱体,制备了一系列组成可控的Co掺杂ZnS纳米线,并采用XRD、TEM、EDS和UV-Vis等表征手段对产物进行表征。实验结果表明,Co掺杂不会改变ZnS的生长方式,Co存在于产物中且含量小于理论值;改变掺杂量可以对ZnS纳米线进行带隙调变,掺杂Co与未掺杂Co的ZnS纳米线都有蓝光-绿光发射。Series of cobalt doped ZnS nanowires were prepared with Ag2S as the catalysts and[(C_(4)H_(9))_(2)NCS_(2)]_(2)Zn_(1-x)Co_(x) as the precursors,and the products were characterized by XRD,TEM,EDS,UV-vis,and etc.The experimental results showed that the cobaltdoping did not change the growth mode of ZnS,cobalt existed in the productand the amountswere less than the theoretical values.The bandgaps of ZnS nanowires could be adjusted by changing the doping amounts.The ZnS nanowires with and without cobalt doping both had blue-green emissions.
