GdVO4　single　crystal　co-doped　with　Nd3+　and　Yb　3+　was　grown　by　the　Czochralski　method.　The　X-ray　powder　diffraction　pattern　of　Nd,　Yb:　GdVO4　crystal　confirms　that　the　as-grown　crystal　is　isostructural　with　pure　GdVO4　crystal,　and　the　result　of　the　optical-homogeneity　measurement　shows　that　this　crystal　is　comparatively　optic　homogeneous.　Its　polarized　absorption　spectrum　and　polarized　luminescence　spectrum　were　measured　at　room　temperature.　The　spectrum　properties　of　Nd　3+　and　Yb3+　in　Nd,Yb:GdVO4　crystal　are　analyzed　by　the　Judd-Ofelt　theory　and　the　reciprocity　method　respectively.　And　energy　transfer　between　Nd3+　and　Yb3+　is　also　discussed.　©　2004　Elsevier　B.V.　All　rights　reserved.
