Photoluminescent properties of Eu3+ doped electrospun CeO2 nanofibers.

In this study, CeO 2 nanofibers and that doped with Eu 3+ were prepared via a facile electrospinning route and annealed at different temperatures ranging from 500 to 900 °C. Their structures were investigated using X-ray diffraction, scanning electron microscopy and transmission electron microscopy. Photoluminescence properties of the nanofibers were studied in detail. It was found that the nanofibers with Eu% concentration of 0.67 mol.% and annealed at 700 °C exhibited the highest intensities of the luminescence peaks between 550 and 650 nm. [ABSTRACT FROM AUTHOR]
