The invention belongs to the technical field of organic photoelectrons, discloses an iridium complex phosphorescent material-based and doped organic ultraviolet detector, and aims at solving the problem of low photo responsivity of the organic ultraviolet detector. The iridium complex phosphorescent material-based and doped organic ultraviolet detector comprises a transparent substrate, a conductive anode, an anode buffer layer, an electron blocking layer, an ultraviolet active layer, a hole blocking layer and a metal anode from bottom to top. The organic ultraviolet detector is characterized in that the ultraviolet active layer comprises the following components in percentage by weight: 56%-60% of an electron donor, 34%-39% of an electron acceptor and 1%-10% of an iridium complex phosphorescent material. The iridium complex phosphorescent material disclosed by the invention has relatively high ultraviolet absorptivity, relatively long phosphorescence lifetime and good thermo-chemical stability, and is effectively combined with a donor-acceptor hybrid material; and through the phosphorescence effect of an iridium complex, the absorbed short-wave ultraviolet light is transmitted to the electron acceptor through triplet energy, so that the production efficiency of excitons is improved; and the photo responsivity of the detector is improved.
