Abstract
Submicron LuBO3:Ce3+ powders and related composite films have been obtained. The phase and granulometric compositions of powders have been determined. The luminescence spectra of the powder under X-ray excitation have been measured and the dependence of the X-ray luminescence intensity on the content of activator impurity (cerium) is established. Using 55Fe and 241Am γ radiation sources, the dependence of the scintillation characteristics of LuBO3:Ce3+ films on the γ quantum energy and cerium concentration has been studied. Features of the γ quantum energy transfer in the medium comprising heavy scintillator particles dispersed in a light organic binder are briefly discussed.
