Preparation of Glasses containing Zn Ions by Sol-Gel Process

摘要

In this work were prepared glasses by using TEOS as precursor and Zn ions were added trough an aqueous solution before the gellification step. The preparation of this system is room temperature and the technique is very simple. These glasses were characterized by x-ray difraction, optic absorption, FT-IR and Raman spectroscopy. The x-ray patterns show the typical amorphous features. The optical absorption shows a shoulder in the UV range corresponding whit ZnO confined to the vitreous matrix. The spectras by FT-IR show characteristic vibrations of Si-O-Si with interaction Zn+2. The Raman scattering let us to identify the formation of the ZnO.
