abstract |
The present invention relates to a detection layer on a substrate comprising ABX 3 -type and / or AB 2 X 4 -type perovskite crystals, wherein A is at least one from the fourth period or higher period in the periodic table Is a divalent, divalent or trivalent element, preferably Sn, Ba, Pb, Bi; B is a monovalent cation whose volume parameter is sufficient for element A to form a perovskite lattice; X is selected from halide anion and pseudo-halide anion, preferably anion chloride, bromide and iodide, and mixtures thereof. The invention also relates to a method for producing a detection layer, a coated particle comprising perovskite crystals, and a detector comprising the described detection layer. |
