摘　　要：光电化学传感方法兼有光学与电化学分析方法的优点,如高灵敏度、高信噪比、低成本、易微型化等。本文介绍了光电化学传感原理,综述了近年来该领域应用研究进展。引用文献84篇。Photoelectrohemical（PEC）sensors are techniques based on the quantitative relationships between the PEC responses of the sensors with the concentrations of analytes,which are typically constructed by modifying substrate electrodes with photovoltaic materials,irradiating the modified photoactive materials with UV/Vis light sources and measuring the PEC responses by common electrochemical analyzers.Therefore,PEC sensors possess the advantages of both optical and electrochemical sensing techniques like high signal-to-noise ratio,high sensitivity,low cost,easy miniaturization,and so on.In this paper,we reviewed the recent progress in sensing principles and applications of PEC sensors.
