Thin films of TiO 2 /SiO 2 /organically modified silane (ORMOSIL) composite material were prepared by the sol-gel spin coating technique. Acid catalyzed solutions of y-glycidoxypropyltrimethoxysilane mixed with tetraethoxysilane and tetrapropylorthotitanate were used as precursors. Ellipsometry, thermal gravimetric analysis (TGA), differential thermal analysis (DTA), UV-visible spectroscopy...
Waveguide thin films with thickness more than one and a half micron were prepared by the sol-gel spin coating technique and low temperature heat treatment from relatively high titanium content organically modified silanes (ORMOSIL). The films were analyzed by X-ray diffraction (XRD), ellipsometry, atomic force microscopy (AFM), thermal gravimetric analysis (TGA), UV-visible spectroscopy (UV-vis),...
