摘要：
The synthesis of europium (III) doped nanocrystalline TiO2 films is described. The morphology and structure of the films were determined by transmission electron microscopy (TEM) and the selected area of electron diffraction (SAED) method. The photoluminescence (PL), lifetimes and cathodoluminescence (CL), recorded at room temperature, are reported. It has been found that the cathodoluminescence characteristics are significantly different from the photoluminescence ones. It is concluded that different Eu3+ sites contribute to the optical behaviour of Eu3+: TiO2 films.
