Up-Conversion Luminescence Properties of Ho3+ Doped and Yb3+/Ho3+ Co-Doped Y2WO6 Phosphors
In this article, Ho3+ doped and yb3+/Ho3+ co-doped Y2WO6 phosphors were successfully prepared via high temperature solid method.Their structures were investigated with X-ray diffraction, the up-conversion(UC) excitation from a 980 nm diode laser, and the developed phosphor shown two UC emission bands in the visible region 540 and 643 nm.Based on the result, the intensity of the frequency up-conversion emission was enhanced significantly through co-doping with Yb3+ ions in the Y2WO6∶ Ho3+ phosphor.The dependence of emission intensity on the pump power indicated that the up-conversion emission was a two-photon process.At last, the energy level diagrams was discussed.The results show that Y2WO6 is a promising host material for UC phosphors.
