Abstract

The invention provides a visible blind ultraviolet light detector unit and an array. The visible blind ultraviolet light detector unit comprises an oxide substrate, a first electrode and a second electrode, wherein the band gap of the oxide substrate is 3-5 electron volt; the first electrode and the second electrode are arranged on the surface of the oxide substrate; and the second electrode is provided with a through hole. The electrode material of the visible blind ultraviolet light detector unit can be metal, graphite or other conductive material. The visible blind ultraviolet light detector array comprises multiple visible blind ultraviolet light detector units, and the second electrodes of the multiple visible blind ultraviolet light detector units are electrically connected to form a net-like structure. Due to the visible blind ultraviolet light detector array, scanning detection, imaging and tracking on a target in visible and infrared light environments can be realized.

Description

technical field [0001] The invention relates to the field of ultraviolet light detectors, in particular to a visible-blind ultraviolet light detector. Background technique [0002] Since the visible-blind ultraviolet light detector is not interfered by visible light and infrared light, it can detect ultraviolet light in the environment of visible light and infrared light, so it has very important and extensive applications in the fields of scientific research, military and national defense. [0003] The inventors of this patent have reported visible-blind ultraviolet photodetectors with fast-response perovskite oxide single crystals with rise times of nanoseconds and picoseconds, for example Document 1: J.Xing et al., Optics Letters, Vol.32, No. .17,2526(2007); Document 2: Kun Zhao et al., Appl.Phys.Lett., 89,173507(2006); Chinese Patent Application No. 201010107349.7 and Chinese Patent Application No. 200510082702.X disclose several ultraviolet light detectors . But so fa...
