A3bx5, a2bx4, abx3, and ax halide scintillators doped with transition metal ions

A scintillator material comprising a composition of one of Formulas (I), (II), (III) or (IV):

• A2B1-iX4:Di, (I),
• AB1-iX3:Di, (II),
• A1-iX:Di, (III), or
• A3B1-iX5:Di, (IV);
• wherein:
• 0.0001≤i≤0.9999;
• A is one or more monovalent cations selected from the group consisting of Tl, In, Li, Na, K, Rb, and Cs;
• B is one or more divalent cations selected from the group consisting of Be, Mg, Ca, Sr, Ba, Zn, Cd, and Hg;
• X is one or more halides selected from the group consisting of F, Cl, Br, and I, subject to the proviso that when the scintillator material comprises a composition of Formula (III), X comprises at least one halide of the group consisting of F, Cl, and Br;
• and
• D is one or more dopant ions selected from the group consisting of Zn, Cd, Hg, Cu, Mn, and Ga, subject to the proviso that D is not the same as B.
