Claims6
A method of forming an elpasolite scintillator, the method comprising:
- forming a stoichiometric elpasolite scintillator crystal from a nonstoichiometric melt, wherein the stoichiometric elpasolite crystal and the nonstoichiometric melt comprise an alkali metal and a concentration of the alkali metal in the nonstoichiometric melt is greater than a concentration of the alkali metal in the stoichiometric elpasolite scintillator crystal, wherein the elpasolite scintillator crystal comprises Cs2LiLnZ6, wherein Z comprises at least one of F, Cl, Br, and I and Ln comprises at least one of Y, La, Ce, Gd, Lu, and Sc.
