Abstract:In order to improve optical property of the multi-walled carbon nanotubes (MWNTs), MWNTs were decorated with europium oxide (Eu2O3) nanoparticles by using co-deposition method. The MWNTs/Eu2O3 composites were examined by XRD, scanning electron microscopy, transmission electron microscopy, and VUV-Vis Luminescence spectroscopy and citric acid (CA) molecules were introduced onto the surface of MWNTs. The results show that there are many oxygenated functional groups on the surface of the MWNTs after the treatment of mixture acid, such as carboxy, hydroxl, carbony and amidocyanogen. The results of electron microscopy illuminate that the MWNTs are coated by nano-europium oxide after annealed at 750℃. The MWNTs/Eu2O3 composite emits much strong red light at about 610 nm under UV excitation.
