摘要

成功制备了氧化锌（ZnO）纳米棒阵列(NRAs)/ZnO量子点(QDs)/聚3-己基噻吩（P3HT）与金纳米颗粒（Au NPs）结合的自供电混合等离子体光电探测器。Au NPs的加入提高了ZnO NRAs/ZnO QDs/P3HT复合光电探测器的光响应性能。最佳ZnO NRAs/ZnO QDs-Au(250) NPs/P3HT有机-无机杂化等离子体光电探测器在525 nm光照和零偏置电压下的光暗比为2450，响应率为46 mA/W，比探测率为1.88 × 1011 Jones。该研究为利用金属纳米颗粒提高有机-无机杂化光电探测器的性能提供了新的见解。

Performance improvement of ZnO nanorod arrays / ZnO quantum dots / P3HT hybrid photodetector by Au nanoparticles

Self-powered hybrid plasmonic photodetectors based on Zinc oxide (ZnO) nanorod arrays (NRAs)/ZnO quantum dots (QDs)/poly(3-hexylthiophene) (P3HT) incorporated with gold nanoparticles (Au NPs) were successfully fabricated. The photoresponse performance of the ZnO NRAs/ZnO QDs/P3HT hybrid photodetectors was enhanced by the incorporation of Au NPs. The optimal ZnO NRAs/ZnO QDs-Au(250) NPs/P3HT organic-inorganic hybrid plasmonic photodetector exhibits a photo-to-dark current ratio of 2450, a responsivity of 46 mA/W and a specific detectivity of 1.88 × 10¹¹ Jones under 525 nm light illumination and zero bias voltage. This study offers novel insights into the utilization of metal nanoparticles to enhance the performance of organic-inorganic hybrid photodetectors.
