Abstract: 
In this investigation, using copper source; Cu(NO3)2.3H2O and by employing sol gel technique consist hydrolyze and polycondensation steps of TEOS and determination of total molar ratio of component, H2O/TEOS = 6.2, ETOH/TEOS= 1.3, copper ions are doped on the silica matrix. Copper oxide particles are produced from decomposition of copper nitrate by thermal treatment that finally is doped on the silica matrix. Using FT IR, Uv vis spectroscopy and X raydiffraction (XRD), the effect of copper species and oxidic support were analysed Average particle size were determinated about 180-200 nanometer by TEM micrograph too. The loss of water "and hydroxyl groups have changed optical properties of copper ions in silica matrix that are observed as variation of monolite color and spectroscopic properties.
