چکیده انگلیسی
Ca1-xTiO3:xEu3+ nanoparticles (NPs) with the size ranging from 27Â nm to 135Â nm were prepared by means of a chemical co-precipitation method. The structural and optical properties of the NPs were investigated, and the influence of Eu doping content and sintering temperature on the photoluminescence of the Ca1-xTiO3:xEu3+ NPs were examined. An obvious red emission band centered at 615Â nm were observed under the excitation with 395Â nm for the Ca1-xTiO3:xEu3+ NPs. X-ray photoelectron spectroscopy analyses suggest that Eu3+ is incorporated into not only the Ca-site, but also Ti-site of CaTiO3 crystal lattice. Our study shows the promise of the Ca1-xTiO3:xEu3+ NPs as a red nanophosphor.
