Abstract

According to the ultraviolet radiation dose monitor, the lower electrode serves as an auxiliary electrode to cooperate with a device to work and is used for controlling electric fields in the organic semiconductor layer and the insulating layer; the insulating layer blocks communication between the lower electrode and the organic photochromic material-polymer composite film layer, and current carriers in a channel between the upper electrode groups are prevented from flowing to the lower electrode. The upper electrode group controls the electric fields of the organic photochromic material-polymer composite film layer and the organic semiconductor layer; the organic photochromic material-polymer composite film layer is used as a dielectric layer, when the device works, the properties of the structure and the like of the organic photochromic material are changed and charges are stored when the device is irradiated by ultraviolet light, so that the transmission current between the upper electrode groups is changed, and the current is not changed under the illumination of which the wavelength is greater than that of ultraviolet light or under the dark condition; changes of channel currents between the upper electrodes are in one-to-one correspondence with ultraviolet radiation doses, and the cumulant of ultraviolet radiation can be directly reflected.
