Using　tungstate　(Na2WO4　center　dot　2H(2)O)　and　mesoporous　silica　dioxide　(SBA-15)　as　tungsten　raw　material　and　hard　template　respectively,　tungsten　oxide　nanoplates　with　nano-pits　were　successfully　synthesized　in　the　acidic　condition　by　a　modified　dipping-reduction　method.　The　composition,　morphology　and　optical　properties　of　as-prepared　products　were　characterized　by　X-ray　diffraction　(XRD),　energy　dispersive　X-ray　(EDX),　scanning　electron　microscope　(SEM),　high　resolution　transmission　electron　microscopy　(HRTEM)　and　ultraviolet-visible　transmission　spectrum　(UV-Vis).　Results　showed　that　the　products　were　single　crystal　tungsten　oxide　nanoplates　with　nano-pits　which　had　higher　transmission　rate　in　the　near　UV-visible　region.　Furthermore,　the　WO3　thin　films　changed　from　the　monoclinic　to　monoclinic　phase　and　orthogonal　phase　with　the　increase　of　sintered　temperature,　and　the　UV-visible　light　transmittance　increased　with　sintered　temperature　of　WO3　thin　film.
