Abstract
The present disclosure relates to a detection layer on a substrate. For example, a detection layer may include perovskite crystals of the type ABX3 and/or AB2X4. A may include at least one monovalent, divalent or trivalent element from the fourth or a higher period in the periodic table and/or mixtures thereof. B may include a monovalent cation, the volumetric parameter of which is sufficient, with the respective element A, for perovskite lattice formation. X may be selected from the group consisting of anions of halides and pseudohalides. The layer may have a thickness of at least 10 μm.
