Abstract

A detector for high-energy radiation, e.g., for x-radiation and/or UV radiation, may include (a) a substrate having a first electrical contact, (b) optionally a first intermediate layer, (c) a layer including an organic matrix of a photoactive material and insoluble scintillator particles distributed substantially homogeneously in the organic matrix, (d) optionally a second intermediate layer, and (e) a second electrical contact, wherein the mixture ratio between the scintillator particles and the organic matrix in layer (c) is selected in such a way that the intermediate space filled with the organic matrix has a distance between two scintillator particles that corresponds to at most five times the depth of penetration of the emitted radiation of the scintillator particles. A method for producing a corresponding detector is also disclosed.
