Abstract
A single crystal scintillator with perovskite structure is described. The crystal is formed by crystallisation from the liquid and has the composition CexLu(1−x−z)Az Al(1−y)ByO3 where A is one or more of the elements selected from the group comprising Y, Sc, La, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, In, and Ga; and B is one or more of the following elements selected from the group comprising: Sc and Ga. The crystal scintillator exhibits a high density and a good scintillation response to gamma radiation.
