Abstract

The present invention provides a visible light and ultraviolet selectivity photoelectric detector. The detector comprises an ultraviolet detection portion, a thin film transistor and a transverse visible light detection portion which are arranged on an insulation substrate. The structure of the detector is reasonably designed, the ultraviolet detection portion, the thin film transistor and the transverse visible light detection portion are integrated on one substrate, and an ultraviolet detection function layer is taken as the channel layer of the thin film transistor so as to shorten the size of the device and optimize the structure of the device, the thin film transistor is employed to realize selection of visible light and ultraviolet detection and improve the detection efficiency.

Description

technical field [0001] The invention relates to a sensor, in particular to a visible light and ultraviolet selective photodetector. Background technique [0002] A photoelectric sensor generally consists of two parts: a processing path and a processing element. Its basic principle is based on the photoelectric effect, which converts the measured changes into changes in optical signals, and then further converts non-electrical signals into electrical signals with the help of photoelectric elements. The photoelectric effect refers to irradiating an object with light, which can be regarded as a series of photons with a certain energy bombarding the object. At this time, the photon energy is transferred to the electron, and the entire energy of a photon is absorbed by one at a time. When the electrons are absorbed, the state of the electrons will change after they get the energy transmitted by the photons, so that the object irradiated by the light will have a corresponding ele...
