摘要
Photoluminescence of thin crystalline TiO2 films was studied. The films contained an anatase phase and were grown by the atomic layer deposition method on different single crystal substrates. A polarised re-combination emission of self-trapped excitons was observed in the films at 5 K. A comparison of the obtained spectra with those of the single crystal anatase allowed determining crystallite orientations in the films. Results were consistent with the X-ray diffraction and reflection high-energy electron diffraction data.
