摘要：
Three thicknesses of TiO2 films, 174, 195, and 229 nm, were deposited onto quartz substrates by sol-gel spin coating method. The as-deposited thin films were characterized by nano-crystallite with different sizes (19-46 nm) and relatively high porous structure. Optical constants were determined and showed the lowest refractive index of 1.66 for the as-prepared films that ever reported till now. Obtained results were discussed through current theoretical ideas.
