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 lamps.
