Descripción: On this work we propose a route to synthesize a silica system by using Sol Gel process in acidic and alkaline media -starting from TEOS as precursor in both cases- allowing visible light diffraction. Incorporation of nanometric silica spheres prepared by hydrolysis- condensation reactions with ammonium hydroxide as morphologic catalyst was made in a gel matrix with vanadium ions as network modifiers prepared by hydrolysis-condensation reactions but in acidic media. The size of monodisperse submicrometric spheres prepared is in the range of the visible light. A comparison between monoliths obtained by commercial nanospheres (OPTA) acidified and those obtained from TEOS/submicrometric spheres prepared is presented, both systems were dried at room temperature and with a temperature rate.
