Effect of compressive stress inducing a band gap narrowing on the photoinduced activities of sol–gel TiO2 films
MN Ghazzal, N Chaoui, M Genet, EM Gaigneaux… - Thin Solid Films, 2011 - Elsevier
TiO2 thin films grown on different kinds of substrates were obtained by sol–gel process. X-
ray diffraction revealed that the TiO2 lattice parameter c decreased continuously, indicating
a continuous variation in the compressive stress, a negligible compressive stress of the film
grown onto Soda-Lime Glass (SLG), medium compressive stress of the film grown onto
BoroSilicate Glass (BSG) and large compressive stress of the film deposited onto the Quartz
Substrate (QS). UV–Vis absorbance spectra exhibited a red-shift of the absorbance edge of …
