Abstract
The scintillation material has a maximum oxygen content of 2,500 ppm and is a compound of formula LnXor LnX:D, wherein Ln is at least one rare earth element, X is F, Cl, Br, or I; and D is at least one cationic dopant of one or more of the elements Y, Zr, Pd, Hf and Bi and, if present, is present in an amount of 10 ppm to 10,000 ppm. The process of making the scintillation material includes optionally mixing the compound of the formula LnXwith the at least one cationic dopant, heating the compound or the mixture so obtained to a melting temperature to form a melt, adding one or more carbon halides and then cooling the melt to form a crystal or crystalline structure. The maximum oxygen content of the scintillation material is preferably 1000 ppm.
