| 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10mmol/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...

| 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 tha... |
