TiO₂ thin films coated on soda-lime glass were prepared by sol-gel process through liquid level method. The effects of different light sources and 175℃ heat-treatment on the hydrophilicity and antifogging ability of TiO₂ thin films were investigated. The results showed that liquid level method was as good as dipping-withdrawing manner；different light sources had various hydrophilicity，antifogging properties；and 175℃ heat-treatment made TiO₂ thin films get better hydrophilicity, antifogging ability. （From : No.1, 2006 Glass & Enamel）
