Abstract: In the first part was produced Zinc Oxide (ZnO) into a glass matrix by using the Sol-Gel Technique at room temperature, these materials were prepared using tetraethyl orthosilicate (TEOS) as precursor, the Zn ions were added before the jellification step trough an aqueous solution of zinc acetate. The optical absorption shows a shoulder in the UV range corresponding whit ZnO confined to the vitreous matrix. The spectra by FT-IR show characteristic vibrations of Si-O-Si with interaction Zn+2. Raman scattering let us to identify and precise the formation of the ZnO. In the second part were immersed glass substrates into an aqueous chemical bath with external controlled temperature, resulting ZnO films were hexagonally structured with energy band gap of 3.3 eV.
