Abstract
The present disclosure relates to a process for fabricating a crystalline scintillator material with a structure of elpasolite type of theoretical composition ABCMXwherein: A is chosen from among Cs, Rb, K, Na; B is chosen from among Li, K, Na; C is chosen from among the rare earths, Al, Ga; M is chosen from among the alkaline earths, X is chosen from among F, Cl, Br, I; y representing the atomic fraction of substitution of C by M and being in the range extending from 0 to 0.05, comprising its crystallization by cooling from a melt bath comprising r moles of A and s moles of B, the melt bath in contact with the material containing A and B in such a way that 2s/r is above 1. The process shows an improved fabrication yield. Moreover, the crystals obtained can have compositions closer to stoichiometry and have improved scintillation properties.
