Paper Abstract

Terbium activated gadolinium oxysulphide phosphor (Gd2O2S: Tb) shows bright green luminescence and high efficiency under X-ray excitation. Phosphor utilization depends on powder characteristics and luminescent properties that are regulated during the synthesis stage. The paper prsents some of our results referring to the synthesis of Gd2O2S: Tb phosphor by solid state reaction route, from oxide precursors. The influence of flux composition and amount as well as the sulphide supplier concentration on phosphor properties was investigated in order to prepare efficient luminescent powders for the manufacture of X-ray intensifying screens for medical diagnosis.
