Enhancement of Visible Upconversion Emission in Y2O3:Er3+-Yb3+ by Addition of Thiourea and LiOH in the Phosphor Synthesis
Spherical like Y2O3 nanostructures doped with Er3+ and Yb3+ ions have been synthesized by a facile hydrothermal method. The samples were prepared by using different precipitant agents in the synthesis process. The phosphors were characterized by X-ray diffraction (XRD), scanning electron microscopy...
