Synthesis and luminescent properties of low concentration Dy3+:GAP nanophosphors
چکیده انگلیسی

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 xDy3+: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.
