Abstract: PVP／Gd(NO3)3·Eu(NO3)3 composite fibers were prepared by electrospinning technique with Gd(NO3)3·6H2O, Eu(NO3)3·6H2O and PVP as starting materials. After calcining the above precursor fibers, Gd2O3:Eu3+ fibers were successfully obtained. The Gd2O3:Eu3+ micro／nano fibers were characterized by SEM, FTIR, XRD, TG-DTA and luminescence spectra, respectively. Results show that the crystalline phase and morphology of Gd2O3:Eu3+ fibres are greatly changed by the calcination temperature.
