Preparation and Luminescence Property of Multi-Walled Carbon Nanotubes/Europium Doped Yttria Oxide Hybrids

Abstract:

In order to improve their optical property, multi-walled carbon nanotubes (MWNTs) were decorated with europium doped yttria oxide (Y2O3:Eu3+) nanoparticles by co-deposition method, and the products were examined by X-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM) and luminescence spectroscopy. Experimental results illuminate that MWNTs can be decorated by the Y2O3:Eu3+ nanoparticles at annealed temperature of 600 and 750°C, respectively. The optical property of MWNTs/Y2O3:Eu3+ nanohybrids shows the most excellent when the MWNTs concentratin is 0.5 wt.% and the molar ratios of Eu to Y is 5:95.
