Fabrication and Luminescence Properties of Y2O3:Eu3+/AAO Composite


Article Preview

Uniform Eu3+ doped Y2O3 nanowires with diameters of 50 nm in the anodic aluminum oxide template (AAO) have been fabricated. The Y2O3:Eu3+/AAO composite nanowires were characterized by using powder X-ray diffraction (XRD), scanning electron microscope (SEM) and spectrofluorometer techniques. The results indicate that with the increasing annealing temperature and time the excitation band of Eu3+ in Y2O3: Eu3+/AAO composite blue shifted, the intensity ratio of 5D0-7F2 to 5D0-7F1 decreased and the lifetime of the Eu3+ ions in composite became longer. In the composite annealed at 1000 °C, two spectral components were detected, corresponding to two different local environments, i.e. the Eu3+ ions in cubic phase and in amorphous phase, respectively.
