摘要：

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.
