A novel class of high energy detecting materials.

摘要

An elpasolite phosphor is provided corresponding to the general formula : A2-yB1+yMe<3><+>X6:xD wherein : A = a monovalent ion B = a monovalent ion A is different from B Me<3><+> = a trivalent ion D is a dopant X is at least one of F, Cl, Br and I 0 /= 4. An elpasolite phosphor corresponding to the general formula above is especially useful in the production of prompt emitting X-ray screens and in the production of X-ray energy storage screens.
