The excitation and diffusion reflection spectra of GdVO

were measured at room temperature. The influences of the doping method and sintering atmosphere on the excitation spectrum of GdVO

were studied. The blue shift and intensity proportion change of the excitation bands

which are due to the effects of acid and deduced sintering atmosphere

are interpreted

the source of the bands at 200～350nm and the possible energy transfer of GdVO

were discussed. The polycrystalline GdVO

was prepared by the high-temperature solid reaction. Using X-ray diffraction (XRD) data

the lattice parameters

calculation gives the estimation density
