摘　　要：紫外光电探测器(UVPDs)能够将紫外光信号转变为电信号来实现紫外光的检测,普遍应用于环境监测、无线通讯、生物等研究领域.自供电UVPDs无需外加电源驱动即可实现对紫外光的检测,能满足新一代器件尺寸小、能耗低、轻型化、集成化的需求.TiO_(2)是一种宽带隙的多功能半导体,其本身具有独特的紫外光吸收特性,并且随着TiO_(2)材料的不断发展,TiO_(2)基UVPDs也成为紫外探测领域研究中的热点之一.本文综述了以本征TiO_(2)、掺杂型TiO_(2)、贵金属改性TiO_(2)、TiO_(2)异质结复合物(例如复合MgO、复合NiO、复合金属及合金、复合聚合物)等作为材料的自供电UVPDs取得的研究成果,并对其发展进行了展望.UV photodetectors(UVPDs)can achieve the detection of UV light by converting UV signals into electrical signals,and can be widely used in environmental monitoring,wireless communication,biology,military and other research fields.Self-powered UVPDs can detect the UV light without external power supply,which can meet the requirements of the new generation of devices with small size,low energy consumption,lightweight and integration.TiO_(2) is a kind of wide-band gap multi-functional semiconductor,which has unique UV light absorption characteristics.With the continuous development of TiO_(2) materials,TiO_(2)-based UVPDs has become one of the hot spots in the field of UV detection.In this paper,the research achievements of self-powered UVPDs using intrinsic TiO_(2),doped TiO_(2),noble metal modified TiO_(2),TiO_(2) heterojunction composites(such as composite MgO,composite NiO,composite metal and alloy,composite polymer)as materials were reviewed,and the development of the self-powered UVPDs was also prospected.
