Systematic interconnected web-like architecture growth of sprayed TiO2 films.
Systematic improvement in interconnected web-like architecture with thickness of TiO2 films synthesized by spray pyrolysis method is reported and characterized for the structural, optical, surface morphological, and wettability properties. Deposited TiO2 films were crystalline with [120] direction orientation, uniform and adherent to the glass substrate. Interestingly, with increase in film thickness, fuzzy and blurred web-like architecture becomes more clear and sharp with well-defined boundaries. The band gap energy was decreased with increase in film thickness. Change in surface architecture resulted into smaller surface wettability in thick film compared to thin one.
