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.

Abstract: A detection apparatus is provided for detection of x-ray radiation, with a lower layer arranged between a lower electrode and a middle electrode. In an embodiment, the lower layer includes at least one first perovskite. In an embodiment, a first voltage is able to be applied between the lower electrode and the middle electrode; and an upper layer is arranged between an upper electrode and the middle electrode. The upper layer features at least one second perovskite and a second voltage is able to be applied between the upper electrode and the middle electrode. Finally, an evaluation device, which is coupled to the upper layer and the lower layer, is embodied to detect an interaction of x-ray radiation with the first perovskite and an interaction of x-ray radiation with the second perovskite.
