摘 要：Ca1-xTiO3:xEu3+ nanoparticles（NPs） with the size ranging from 27 nm to 135 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 615 nm were observed under the excitation with 395 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 Ca TiO3 crystal lattice. Our study shows the promise of the Ca1-xTiO3:xEu3+ NPs as a red nanophosphor.
