Carbon　nanotubes(CNTs)　were　successfully　introduced　into　silica　gel　glass　matrix　by　physically　doped　sol-gel　technique.　The　characterization　of　structure　and　spectra　of　the　CNTs　doped　composites　were　carried　out　by　X-ray　diffraction,　transmission　electronic　microscope,　UV-Vis　spectra,　IR　spectra　and　Raman　spectra.　The　results　show　that　CNTs　are　homogeneously　dispersed　in　the　silica　gel　glass　matrix　and　the　sol-gel　processing　does　not　appear　to　affect　the　intrinsic　structure　of　CNTs.　The　introduction　of　CNTs　doesn＇t　make　any　noteworthy　changes　in　the　UV-Vis　and　IR　spectra　of　silica　gel　glass　matrix.
