Ultraviolet (UV) photodetector

Abstract

The UV domain of the optical spectrum is divided into the following subdomains: UV-A subdomain 400-320 nm, UV-

B 320-280 nm, UV-C 280-200 nm, which correspond to the bactericidal domains, which is of major importance in the detection and optical radiation dosimetry in antibacterial treatment. The result of the invention consists in ensuring the selectivity of the photoreceptor to ultraviolet radiation for the subdomains of the optical spectrum A, B, C

depending on the composition of the MgxZn1-xO layer by creating a bandgap gradient of at least 3*105 eV/cm in the active region of the detector in the photoreceptor structure of the transparent-window film with a difference of the energy

bands compared to the absorption film.
