The new material consisting of Gd1.6Dy0.4(WO4)3 incorporated into silica xerogel was prepared via the coprecipitation method. The luminescence properties of the studied material were analyzed by means of emission and excitation spectra, including the result of luminescence lifetimes of Dy(III) ion. The enhanced yellow emission due to the excitation energy transfer from WO42- group to Dy(III) ion upon excitation at exc = 240 nm is the main result of this paper.
