X-ray luminescence of Gadolinium and Europium Silicate-based materials

Abstract

The materials on the basis of gadolinium and europium silicates were investigated to find compositions deciding x-ray luminescence optimum parameters. The colorless Gd2SiO5:Eu monocrystals were obtained by Chochralski method. Their optical and scintillation homogeneity was provided by the proximety of europium distribution coefficient along the ingot to one. Concentration dependence of x-ray luminescence intensity was studied in the Gd2SiO5-Eu2SiO5 system. Effective x-ray luminescence was demonstrated to have the solid solutions of europium oxoorthosilicate (to 10 mol.%) in gadolinium oxoorthosilicate.
