摘要：
Dy3+:GAP (gadolinium aluminum perovskite) powder nanophosphors have been newly synthesized by means of solvothermal process. Spherically shaped particles in the nanometer ranges prepared by this method were evidenced by X-ray diffraction (XRD) and transmission electron microscopy (TEM) measurements. The synthesis, structural and luminescent properties along with chromaticity coordinates of the nanophosphor samples with the compositions xDy(3+):Gd(1-x)AlO3 (x = 0.005-0.05) are featured in this paper. Furthermore, the yellow to blue intensity ratio of Dy3+:GAP nanophosphors varies from 1.19 to 1.03. Such luminescent powders are expected to find potential applications such as optical display systems. (C) 2009 Elsevier B.V. All rights reserved.
