摘要: 近年来半导体量子点以其发光效率高、量子点尺寸具有可调的发射波长、特有的光学特性以及分离三角功能状态和光学振子密度大、温度不敏感的光学增益受到人们的极大关注。本文利用无机钙钛矿量子点(CsPbBr3)修饰ZnO基紫外探测器来改善响应时间。结果表明，修饰后的紫外探测器，在400 nm可见光照射下，器件的响应恢复时间反偏为2 s，正偏时间为10 s，恢复时间明显改善。
Abstract: In recent years, semiconductor quantum dots have received great attention due to their high lu-minous efficiency, adjustable emission wavelength of quantum dot size, unique optical character-istics, and separation of triangular functional states and optical oscillators with high density and temperature insensitivity. In this paper, the response time is improved by using the inorganic perovskite quantum dots (CsPbBr3) to modify the ZnO based UV detectors. The results show that the response recovery time of the modified UV detector is 2 s in reverse and 10 s in positive under 400 nm visible light irradiation, and the recovery time is improved obviously.
