AbstractTiO2: 2%Sm3+ thin films were prepared by oblique angle deposition. X-ray diffraction (XRD), scanning electron microscope (SEM), UV-Vis-NIR spectrophotometer, fluorescence spectrophotometer was employed to characterize the structure and optical properties of TiO2: 2%Sm3+ thin films. The results indicated that these thin films were with anisotropic columnar structure before and after calcination. The optical anisotropy measured by transmission difference (Tp-Ts) at 500nm was increasing from 8% to 33% with calcination. Under ultraviolet excitation (lambda(ex) = 330nm) and commercial 365nm UV lamp excitation, these TiO2: Sm3+ thin films show intense (4)G(5/2)-> H-6(5/2), (7/2), (9/2) emissions of Sm3+. The polarized photoluminescence was anticipated in the anisotropic thin films.
