Photoluminescence Property of ZnO:Eu Hollow Nanofibers Fabricated by Sputtering Using Electrospun PVP Nanofibers as Templates

Abstract:

Eu-doped ZnO (ZnO:Eu) hollow nanofibers were fabricated by sputtering using electrospun PVP nanofibers as templates. The morphologies, crystal configuration, bonding structures and optical properties of the ZnO:Eu hollow nanofibers were characterized, respectively. Raman results indicate that there are many oxygen vacancies and/or interstitial zinc in ZnO:Eu hollow nanofibers. Effect of Eu-doping on vibrating modes of ZnO is attributed to the change of defects and impurities due to incorporation of europium. The high intensity ultraviolet emission and red luminescence of the ZnO:Eu hollow nanofibers are observed due to the random lasing of near-band-gap emission of ZnO and an f-f transition of the Eu³⁺ ions, respectively.
