摘要

采用不同浓度的银溶液对水热方法生长的ZnO纳米线进行了银修饰

并对其形貌、光致发光和光响应特性进行了研究。实验结果表明

随着修饰用银浓度的加大

光致发光的强度减弱。对原生的和用浓度为10 mmol/L的银修饰的ZnO纳米线的光响应进行了测试和比较

发现银修饰的ZnO纳米线在380 nm的响应度达4.6 mA/W

其值是未修饰的ZnO纳米线的75倍

说明银修饰有效地提高了ZnO纳米线的光响应特性。

Abstract

The ZnO nanowires grown via hydrothermal method were modified by Ag with different concentration in solution. The morphology

photoluminescence property

photoresponse of the ZnO nanowire were stu-died. The results exhibited that the intensity of photoluminescence decreases with the increased Ag concentration. The photoresponses of as-grown and modified by Ag of 10 mmol/L nanowires were tested and compared. The responsivity of Ag modified ZnO nanowire was 4.6 mA/W at 380 nm. This value was 75 times larger than that of the as-grown one. The results indicated that photoresponse property of ZnO nanowires can be effectively improved by Ag modifying.
