Pyrene can be transferred at high concentration from a cyclohexane solution into;a mixed titania-surfactant film formed by the sol-gel method. Pyrene forms excimer in a dynamic manner. Excimer formation and other photophysical aspects of the fluorophore in the film are examined. Triton X-100, used to control hydrolysis of titanium isopropoxide, is transferred on the surface of the film, possibly by hydrophobic attraction.
