Description

RE3+ (Tb3+/Ce3+) activated GdPO4 phosphor has been synthesized by hydrothermal route at 150 °C using citric acid as chelating agent. The synthesized phosphor has been characterized by TEM, TG/DTA, Powder X-ray diffraction and photoluminescence spectra. GdPO4 displayed green emission after doping with Tb3+. The influence of γ-radiation on structural and photoluminescence properties of GdPO4:Tb3+, Ce3+ was also examined at 5 and 300 kGy. Quenching of PL intensity was observed in GdPO4:Tb3+, Ce3+ after exposure to γ-radiation. Moreover, this phosphors exhibited high structural stability upon γ-radiation exposure. (author)
