The YPO₄:xDy³⁺,0.06Eu³⁺ phosphors were syn thesized by hydrothermal m ethod.The prepared products were studied by X-ray powder diffraction (XRD), scanning electron microscopy (SEM),energy dispersive spectrometer (EDS),photoluminescence (PL) spectroscopy and long-lasting phosphorescence.The results by XRD indicate tha t YPO₄:0.05Dy³⁺,0.06Eu³⁺ belongs to a tetragonal crystal system.Ph otoelectron spectroscopy measurement from YPO₄:0.05Dy³⁺,0.06Eu³⁺ reveals the b inding energy of the elements onto the product surfaces.When excited by 234nm,the characteristic e mission peaks of Eu³⁺ due to the transitions of 5D₀→⁷F₁ at 592nm and ⁵D₀→⁷F₂ at 618nm were observed in the emission spectra of YPO₄:xDy³⁺,0.06Eu³⁺.The emission spectra of YPO4: 0.06Dy³⁺,0.06Eu3＋ excited by 354nm are composed of blue (⁴F9/2→⁶H15/2,486nm) and yellow (⁴F9/2→⁶H13/2,575nm) emission peaks of Dy³⁺,orange (⁵D₀→⁷F₁,592nm) and red (⁵D₀→⁷F₂, 619nm) emission peaks of Eu³⁺,and white light emission can be observed.Th e energy transfer is confirmed to occur between Dy³⁺ and Eu³⁺ when the decay spectrum of Dy³⁺ is fitted by a double-exponential function.From Commission Internationale de L′Eclairage (CIE) chromaticity diagram,it is noted that white light can be achieved in the emission spectra of YPO₄:0.05Dy³⁺,0.06Eu³⁺ phosphor at 234nm exci tation．
