本文报道了一种基于ZnO纳米棒阵列/钙钛矿电池结构的紫外-可见可调的光电探测器,其中ZnO纳米棒阵列采用水热法制备并在不同气氛下退火.基于电池结构的钙钛矿光电探测器具有较好的光电响应重复性和稳定性.ZnO纳米棒阵列真空退火的器件在可见光区域达到了1014 Jones的响应度,而ZnO纳米棒阵列在空气中退火的器件在紫外光区域,尤其在365 nm处有较好的探测性能.进一步研究发现,通过不同氛围退火,实现了紫外-可见可调的光电探测性能.以上结果表明ZnO纳米棒阵列/钙钛矿光电探测器在紫外和可见光区域存在潜在应用.
In this paper, we report a UV-visible photodetector based on a ZnO nanorod array / perovskite cell structure, in which the ZnO nanorod arrays are prepared by hydrothermal method and annealed in different atmospheres. Calcium-titanium The photodetector has good repeatability and stability of photoelectric response.ZnO nanorod array vacuum annealed devices in the visible region to achieve a 1014 Jones response, and ZnO nanorod arrays in air annealing device in the ultraviolet region , Especially at 365 nm.Further study found that the UV-visible tunable photodetection performance achieved by different atmosphere annealing.The above results show that the ZnO nanorod array / perovskite photodetector in the ultraviolet And the visible region there is potential applications.
