摘要: Novel Dy3+-doped Gd(PO3)3 white light phosphors each with an orthorhombic system are successfully synthesized by solid-state reaction. The luminescence properties of white-light Gd1-x(PO3)3:xDy3+ (0<x≤ 0.25) under vacuum ultraviolet (VUV) excitation are investigated. The strong absorption at around 147 nm in excitation spectrum energy can be transferred to the energy levels of Dy3+ ion from the host absorption. Additionally, the white light phosphor is activated by a single Dy3+ ion. Therefore, the luminescence of Gd1-x(PO3)3:xDy (0<x≤ 0.25) under VUV excitation is effective, and it has the promise of being applied to mercury-free lamp.
