TEM images and XRD patterns of the films. (a) TEM images of the ITO/nc-TiO2/CdS(5) film at low and high (inset) magnifications. (b) XRD patterns of the as-prepared ITO/nc-TiO2 and ITO/nc-TiO2/CdS(10) films. C represents CdS. The large particles are titania Degussa P25 nanoparticles. The small dark spots belong to CdS nanoparticles with diameters of about 10 to15 nm.
