The SrMoO₄:Eu³⁺,SrMoO₄:Tb 3+,Eu³⁺ phosphors were synthesized by hydrothermal method. The crystal structure morphology and luminescent properties are studied by X-ra y diffraction (XRD),scan electron microscope (SEM),photoelectron spectroscopy (PES),photoluminescence (PL) spectroscopy and long-lasting phosph orescence.The results by XRD indicate SrMoO₄:0.05Eu³⁺,SrMoO₄:0.10Tb³⁺,0.05Eu³⁺ belong to a tetragonal crystal system.The PES results reveal that the as prepared SrMoO₄:0.10Tb³⁺,0.05Eu³⁺ phosphors are mainly composed of corresponding elements of molecular formula and no other impu rity is detected.The emission spectra of SrMoO₄:xEu³⁺ excited by 364nm,385nm,397nm,419nm,467nm and 537nm are composed of ³T₁,³T₂-¹A₁ charge transfe r peak of [MoO₄] atomic group(536nm,green) and ⁵D₀→ 2F₂→⁷F₁(593nm,orange red),⁵D₀→⁷F₂(615nm,red),and ⁵D₀→⁷F₃(646nm,red) emission peaks of Eu³⁺. The emission spectra of SrMoO₄:0.10Tb³⁺,0.05Eu³⁺ excited by 243nm ,253nm,288nm,320nm and 396nm are composed of ⁵D₄→⁷F₆(489nm,blue), ⁵D₄→⁷F₅(546nm,green),⁵D₄→ 7F₄(582nm,yellow) of emission peaks Tb³⁺ and ⁵D₀→⁷F₁(593n m,orange red),⁵D₀→⁷F₂(615nm,red),and ⁵D₀→ ⁷F₃(646nm,red) emission peaks of Eu³⁺.By adjusting excitation spectrum of SrMoO₄:0.10Tb³⁺, 0.05Eu³⁺,tunable emission colors are realized in a large color gamut,in which energy transfer from Tb³⁺ to Eu³⁺ is observed and discussed in detail.
