The　neodymium　ions　doped　gadolinium　vanadate　(Nd　:　GdVO4)　single　crystals　were　successfully　grown　by　Czochralski　method.　Chemical　etching　technique　was　used　to　reveal　the　dislocation　structure　of　the　crystals.　An　average　dislocation　density　of　(100)　plane　is　600　pits/mm(2).　The　crystal-morphology　can　be　used　to　determine　crystal　orientation　accurately　with　simple　optical　method.
