Abstract

Photoconductivity of ТiO2 thin films is investigated in experiment. The excitation is performed by both a continuous Hg quartz lamp and laser sources. The photoconductivity kinetics and spectrum are investigated. The multi relaxation character of photoconductivity kinetics is revealed. The photoconductivity spectrum is measured in the 250 ÷ 420 nm range. The nature of the observed features is discussed.
