In　this　paper,　the　non-doped　and　doped　Yb3+　of　GdVO4　crystals　whose　polycrystalline　material　was　synthesized　by　the　liquid-phase　reaction　method　were　grown　by　the　Czochralski　method.　The　sinter　temperature　can　be　concluded　by　thermal　analysis.　The　influence　of　the　thermal　gradient　on　the　crystal　quality,　the　segregate　coefficient　of　Yb3+　ion　in　the　crystal,　the　transparence　spectrum　of　the　non-doped　GdVO4　crystal　and　the　effect　of　lattice　structure　on　the　absorption　spectra　and　the　fluorescence　spectra　are　discussed.　(C)　2003　Elsevier　B.V.　All　rights　reserved.
