摘要：
Spherical-shaped, Tb3+/Al3+ codoped Gd2O3 phosphor particles were synthesized using a urea homogeneous precipitation method. Field emission scanning electron microscopy measurements confirmed the formation of nearly-uniform spherical particles with sizes in the range, 250 +/- 50 nm. In this study we examined the effects of the Al3+ codoping concentration on the photoluminescence emission of Tb3+ doped Gd2O3 phosphor particles. The results confirmed that incorporating Al3+ into Gd2O3:Tb3+ phosphor is highly favorable for improving the emission of the synthesized Gd2O3:Tb3+ phosphor particles. In addition, the simple approach for the luminescence enhancement given here can be extended to the other phosphor systems. (C) 2012 Elsevier B. V. All rights reserved.
