摘要

采用溶液旋涂和高真空蒸镀工艺制备了平面和体异质结混合型器件结构的三基色有机光电探测器, 利用实验分步探究其不同组分的活性层厚度、混合度以及前置吸收层对器件光电特性的影响.在此基础上, 对三基色有机光电探测器进行样品制备及测试.结果表明, 混合型结构的光电探测器件对光的吸收几乎覆盖整个可见光区域, 对350~700 nm范围的光呈现出类似于平台式的宽光谱响应.该器件在-1 V偏置电压下, 对红、绿、蓝光的比探测率分别为2.89×1011 Jones、3.22×1011 Jones、1.97×1011 Jones, 表明该器件对红、绿、蓝光有较好探测效果, 尤其对红光的探测率有3~4倍提升.

Abstract

By adopting solution spin coating and high-vacuum evaporation process, trichromatic organic photodetectors with planar and heterojunction hybrid device structures were prepared. The experiment was used to explore the active layer thickness, mixing degree of different components and the influence of the pre-absorption layer on the photoelectric properties of the device. On this basis, sample preparation and testing of trichromatic organic photodetectors were performed. The results show that the absorption of light by the photodetector device of the hybrid structure covers almost the entire visible light region, and exhibits a broad spectrum response similar to that of the platform-type light in the range of 350~700 nm.Under the bias voltage of -1 V, the detectivity of red, green, and blue light are 2.89×1011 Jones, 3.22×1011 Jones, and 1.97×1011 Jones, respectively. It shows that the device has good detection effects on red, green and blue light, in particular, the detectivity of red light rise up 3 to 4 times.
