We report on preparation and characterization of GeO 2 /methyltrimethoxysilane hybrid thin films processed by the sol-gel spin coating technique. Acid catalyzed solutions of methyltrimethoxysilane mixed with germanium isopropoxide have been used as precursors for the hybrid materials. The optical properties of the thin films, including refractive index, thickness, and transparency as well...
Silica-titania hard optical coatings based on titania/organically modified silane composite materials were prepared by the sol-gel spin coating technique. Acid catalyzed solutions of methyltrimethoxysilane mixed with tetrapropylorthotitanate were used as precursors for the silica-titania coatings. Atomic force microscopy, thermal gravimetric analysis, UV-visible spectroscopy, and Fourier transform...
