Abstract

TiO ₂: 2%Sm ³⁺ 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 TiO ₂: 2%Sm ³⁺ 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 (?ex =330nm) and commercial 365nm UV lamp excitation, these TiO ₂: Sm ³⁺ thin films show intense 4G5/2→ ⁶H _{5/2, 7/2, 9/2} emissions of Sm ³⁺. The polarized photoluminescence was anticipated in the anisotropic thin films.
