Synthesis and characterization of Cu-doped TiO2 thin films produced by the inert gas condensation technique

Abstract

The bandgap of thin films Cu-doped TiO2 nanoclusters prepared using the inert gas condensation (IGC) technique have been investigated at various Cu contents. The samples were characterized using XRD, SEM/EDS and UV-visible spectrophotometer. It was found that doping of TiO2 thin film nanoclusters with Cu enhance its optical activity and shift it to the visible region; which makes it useful in photocatalytic applications. 1 Published under licence by IOP Publishing Ltd.
