Thin titania films can be used especially as a component of self-cleaning glass, utilizing photoinduced hydrophilic properties of titanium dioxide surfaces. For the first time thin titania layer on the Pilkington Glass ActivTM was modified with ammonia, thiourea and urea to introduce non- metal elements into titania structure to shift absorption spectrum to visible light region. Contact angles for water on Pilkington glass plates were measured for unmodified and modified titania resulting in noticeable shift of absorption spectrum towards lower energy radiation.
