摘要

为了实现在无外加电源情况下对紫外光的长时间探测，基于WO

纳米片制备了具有自供能特性的紫外探测器。采用水热法在FTO玻璃衬底上成功制备了WO

纳米片阵列，并通过SEM、XRD等手段对样品进行分析，研究结果显示，长度约为2 μm、厚度约为200 nm的单斜相WO

纳米片均匀致密地生长并覆盖在整个衬底表面。制备的WO

纳米片的光吸收范围集中在紫外波段，对330~440 nm的光具有强的吸收能力。以WO

纳米片为工作电极制备了紫外探测器，测试结果表明，WO

纳米片紫外探测器能够在无外加偏压的情况下有效探测紫外光，且具有自供能特性。探测器的光电性能表现出高光响应电流（约为171 μA）和快速响应特性（上升时间约为25.7 ms，下降时间约为38.7 ms），并在多次紫外光开/关下保持良好的稳定性与重复性。

Abstract

In order to achieve ultraviolet detection without power supply， a self-powered ultraviolet detector based on WO

nanosheets is constructed. The uniform WO

nanosheets have been successfully synthesized on fluorine-doped tin oxide substrate via a facile hydrothermal method. Then， the morphology， composition， and structure of the samples are systematically characterized， which indicates that WO

nanosheets are monoclinic with an average length of 2 μm and a mean thickness of 200 nm. Furthermore， the ultraviolet detector based on WO

nanosheets has been fabricated and measured without bias voltage for its photodetection performances， which reveals high values of photocurrent about 171 μA， rapid response with rise time around 25.7 ms and decay time around 38.7 ms， outstanding stability and self-powered property under the cycled irradiation of 365 nm ultraviolet light.
