摘要
外量子效率远远超过100%的有机光电倍增探测器近年来受到了研究者们的广泛关注。首先介绍有机光电倍增探测器的基本结构及其光电倍增机理。有机光电倍增探测器由于其活性层的材料特性不同,可分为小分子基及聚合物基两种类型。针对这两种不同类型的有机光电倍增探测器的研究进展进行综述,详细说明研究者们在改善有机光电倍增探测器量子效率、暗电流、响应速度、光谱性能等方面取得的重要进展。简单介绍了研究者们针对有机光电倍增探测器的工作机理提出的一些不同解释。总结全文并展望了有机光电倍增探测器的发展前景。
Abstract
In recent years, organic photomultiplication photodetectors with external quantum efficiency far exceeding 100% have drawn extensive research attention. This paper firstly presents the typical structures of organic photomultiplication photodetectors and their working mechanisms. Organic photomultiplication photodetectors can be divided into two types depending on the material properties of active layers. One is the small organic molecule photomultiplication photodetector and the other is the polymer photomultiplication photodetector. This paper reviews the progress of these two different types of organic photomultiplication photodetectors. Then, we introduce some important developments in optimizing quantum efficiency, dark current, response speed and spectral performance of organic photomultiplication photodetectors in detail. Later, we briefly show some different explanations proposed by researchers for explaining the working mechanism of organic photomultiplication photodetectors. Finally, we summarize the paper and provide the prospect of organic photomultiplication photodetectors.
