为了提高锑纳米线的紫外光敏感性和光催化性能，制备了掺杂锑的氧化锌纳米线。在紫外光（365 nm，2.33mW cm-2）照射下，ZnO：Sb纳米线的光电流比ZnO纳米线的光电流响应快.在合成的ZnO：Sb纳米线中实现了约48.8倍的光电流与暗电流的最高比率。利用紫外-可见分光光度计对ZnO：Sb纳米线的吸收光谱进行了研究，结果表明，与ZnO纳米线相比，ZnO：Sb纳米线具有较高的吸收比，并具有红移效应。ZnO：Sb纳米线的可见光吸收和紫外光响应性能均优于ZnO纳米线的上级。
Zinc oxide (ZnO) doped antimony (Sb) nanowires have been synthesized for improving ultraviolet sensing and photocatalytic properties. Upon illumination by UV light (365 nm, 2.33 mW cm -2 ), the photoelectric current of the ZnO:Sb nanowires exhibited a rapid photoresponse as compared to that of the ZnO nanowires. A highest ratio of photocurrent to dark current of around 48.8-fold was achieved in the as-synthesized ZnO:Sb nanowires. A UV-visible spectrophotometer was used to investigate the absorbance spectrum of the ZnO:Sb nanowires, which exhibited a high absorbance ratio with redshift effect in contrast to that of the ZnO nanowires. Visible-light photocatalysis and UV photoresponsive properties of the ZnO:Sb nanowires are superior to those of the ZnO nanowires.
