Abstract

X-ray photoelectron spectroscopy (XPS) results are presented on a series of alkali-doped and undoped TiO2 films prepared by the sol-gel technique. TiO2 films are deposited onto Al2O3 and quartz substrates, using titanium isopropylalkoxide as the precursor, by dip-coating from the appropriate solutions. After dipping, the films are dried at 100 degrees C for one day and then heated to 300 degrees C for 30 min. The surface composition of the films is discussed, and the effects of Li, Naand K doping are compared. The effect of doping on the humidity-sensitive electrical properties of the films is evaluated by measuring the current flowing at various relative-humidity values upon application of a constant d.c. voltage.
