A halide scintillator material is disclosed where the halide may comprise chloride, bromide or iodide. The material is single-crystalline and has a composition of the general formula ABX3 where A is an alkali, B is an alkali earth and X is a halide which general composition was investigated. In particular, crystals of the formula ACa1-yEuyI3 where A=K, Rb and Cs were formed as well as crystals of the formula CsA1-yEuyX3 (where A=Ca, Sr, Ba, or a combination thereof and X═Cl, Br or I or a combination thereof) with divalent Europium doping where 0≰y≰1, and more particularly Eu doping has been studied at one to ten mol %. The disclosed scintillator materials are suitable for making scintillation detectors used in applications such as medical imaging and homeland security.
