Eu3+ doped Gd2W2O9 and Gd2(WO4)3 nanophosphors with different concentrations were prepared via a co-precipitation method. The structure and morphology of the nanocrystal samples were characterized by using X-ray diffraction (XRD) and field emission scanning electron microscopy (FE-SEM). The emission spectra and excitation spectra of the samples were measured, the J-O parameters and the quantum efficiencies of the 5D0 level of Eu3+ of the samples were calculated, and the concentration quenching curves of Eu3+ luminescence in different hosts were given. The study results indicate that similar to the Gd2(WO4)3:Eu, the red emission of Eu3+ 5D0 → 7F2 transition in Gd2W2O9:Eu can also be effectively excited by 395 nm near-UV light and 465 nm blue light. So the Gd2W2O9:Eu red phosphors may have a potential application for white light emitting diodes.
