Abstract

This paper discusses the structural, optical, and spectrokinetic characteristics of ceramics based on gadolinium oxysulfide Gd2O2S:RE (RE = Pr, Tb, Eu), obtained by the method of uniaxial hot pressing. It is shown that the composition and conditions of hot pressing affect the parameters of the Gd2O2S lattice and the formation of the predominant grain orientation in the (001) plane of the pinacoid. All the ceramics possess transparency that is high for an anisotropic material (about 40% at a thickness of 1.65 mm) in the intrinsic emission region. The overall x-ray luminescence intensities (relative to CsI:Tl) for the Gd2O2S:Pr,Ce, Gd2O2S:Tb(Ce), and Gd2O2S:Eu ceramics are 50, 160 (120), and 200%, respectively, while the damping time constants are 3.2, 600–700, and 450 µs, respectively.
