传统的氧化锌紫外探测器存在光电流小的问题,由于石墨烯具有较高的载流子迁移率,文中采用一种简便的旋涂退火的方法,使得石墨烯量子点在氧化锌纳米线表面复合.利用石墨烯量子点修饰氧化锌纳米线的表面后,制备的氧化锌基紫外光电探测器在5V偏置电压条件下,在波长为365 nm、功率为1.35 mW/cm2的紫外光照射下,光电流从9.5 μA增加到65 μA,光电流增大了6.8倍,光电流明显提高.这种简单的旋涂退火方法,在有效降低紫外光电探测器加工工艺的同时,提高了探测器的性能,将为下一代可持续绿色发展策略,设计高效率低成本的光电设备提供有益的参考.“,”The photocurrent of traditional ZnO ultraviolet detector is low.Due to the high carrier mobility of graphene,the idea of employing Graphene Quantum Dots as photosensitizers of electron transporting medium was proposed.The phenomenal performance of ZnO-GQD composites was attributed to the efficient immobilization of GQDs on ZnO nanowires via an inexpensive spin-coating method.A simple spinning annealing method was used to make graphene QDS compound on the surface of ZnO nanowires.After the surface of ZnO nanowires being modified by graphene quantum dots,the photocurrent of the ZnO photodetector was increased from 9.5 μA to 65 μA under the condition of 5 V bias voltage and UV irradiation with wavelength of 365 nm and power of 1.35 mW/cm2.The photocurrent was increased by 6.8 times.This simple spinning annealing method reduces the processing technology of UV photodetector and improves the performance of the photodetector,which will provide a beneficial reference for the next generation of sustainable green development strategy and the design of high efficiency and low cost photoelectric equipment.
