The present disclosure is directed to a group of newly discovered intrinsic scintillation compounds. As intrinsic scintillators, these compounds do not require an external activator as a dopant. The new scintillators may include members of two elpasolite families with the general exemplary formulas of A2BMX(6-y)X′y and A3MX(6-y)X′y, (0<y<6). Component A may include at least one element selected from the group consisting alkali elements and thallium (Li, Na, K, Rb, Cs and Tl); Component B may include at least one element, different from the at least one element of component A, selected from the group consisting alkali elements (Li, Na, K, Rb, and Cs); Component M may include at least one element selected from the group consisting tri-valence elements (La, Gd, Lu, Bi, Y); Component X may include at least one element selected from the group consisting halide elements (F, Cl, Br and I); Component X′ may include at least one element, different from the at least one element of component X, selected from the group consisting halide elements (F, Cl, Br and I). The value of y may be in a range between 0 and 6 non-inclusively (i.e. 0<y<6, or y={1, 2, 3, 4, 5}). |
