Abstract�� Transparent TiO_2 thin films were obtained on glass by a liquid phase deposition method(LPD).The crystalline structure,particle size,appearance shape and photo-catalytic activity were characterized by XRD and SEM.The bactericidal experiment of S.Aureus and E.Coli showed that TiO_2 thin films have excellent bactericidal activity without UV irradiation.The films are the best with heat treatment at 400 �� and its bactericidal percentage reaches 99% in 24 h.A preliminary discussion on the bactericidal mechanism is also put forward.
