Optical Properties of Inorganic-Organic Hybrid Silica Gel Glasses Doped with Copper Phthalocyanine

Abstract

Inorganic-organic hybrid silica gel glasses were successfully prepared by the sol-gel method. Copper phthalocyanine and vinyltriethoxysilane were used as optical active material and inorganic glass component, respectively. The absorption spectrum of copper phthalocyanine-doped hybrid glasses was recorded in the spectral range of 200-1000 nm. Optical band gap is determined from the UV-vis optical absorption spectra.
