摘要

High-quality Zn-free and added GdPO_4:Tb~3 green phosphors, i.e., fine size as well as smooth and spherical morphologies, were synthesized by ultrasonic spray pyrolysis. The influence of Zn~(2+) content and annealing temperature on the photoluminescence properties of the GdPO_4:Tb~3 phosphors annealed at 800-1100°C was investigated. The addition of Zn~(2+) for Gd~(3+) was highly effective for improving the photoluminescence properties of GdPO_4:Tb~3. The Zn added GdPO_4:Tb~3 phosphors with Zn/Gd = 0.045/0.805 showed the strongest emission of the prepared phosphors. The emission intensity at 544 nm for the GdPO_4:Tb~3 phosphors with Zn/Gd = 0.045/0.805 annealed at 900 °C was 496% stronger than that at 800 ° C.
