Preparation and Characterization of the Y2O3:Eu3+ Nanowires

Abstract

Abstract: The nanowires of Y₂O₃:Eu³⁺ phosphor were synthesized by using AAO template method. By the observation of the SEM images,the characteristics of morphologies between Y₂O₃:Eu³⁺ nanowires and Al₂O₃ nanowires produced by etching the empty AAO template was compared. The results of the SEM image analysis indicate that each nanowire is composed of a lot of agglutinating nanoparticles. At the same time,the Y₂O₃:Eu³⁺ nanowires were confirmed by EDX and PL spectra. The results of the XRD and SAED show that Y₂O₃:Eu³⁺ nanowires are mainly composed of polycrystalline materials with a cubic phase.
