Ge quantum dots (QDs)-doped TiO2films were prepared by ion-beam sputtering. TEM results showed Ge QDs were in a uniform size distribution and high density. XPS indicated that Ge incorporated in the TiO2films was in elemental form. The Stranski–Krastanov growth mode was accounted for the growth of Ge QDs in TiO2films by AFM analysis. Optical absorption spectra exhibited the optical response of the Ge QDs-doped TiO2films was shifted from UV to the near infrared region, suggesting a good optical absorption property.
