The Eu3+-doped Li2WO4 was prepared by solid phase reaction from Li2CO3, WO3 and Eu2 O3, and characterized by using powder X-ray diffractometry. The emission and excitation spectra were measured. The luminescence properties of Eu3+ -doped Li2 WO4 and energy transfer mechanism were discussed. Suitable doping improves luminescence properties and ionic conductivity of Li2WO4.
