A new inorganic scintillating material is provided represented by the formula Ln (l-m-n) Hf n Ce m A (3+n) , where A is Br or CI, or I, or a mixture of at least two halogens of the group, Ln is an element from the group: La, Nd, Pm, Sm, Eu, Gd, Tb, Lu, Y. A new crystal scintillator is also provided represented by the formula Ln (l-m) Ce m A 3 : n⋅Hf 4+ , where Ln (l-m) Ce m A 3 represents the chemical composition of the matrix material, A is Br, or CI, or I, or a mixture of at least two halogens from the group, Ln is an element from the group: La, Nd, Pm, Sm, Eu, Gd, Tb, Lu, Y; Hf 4+ is a dopant. A radiation detector comprising a scintillating element based on the novel inorganic scintillating material is also provided. |
