Abstract: In this study, two kinds of solvents were respectively selected to dissolve Poly(vinyl pyrrolidone) and rare earth nitrates, then the solutions were used to fabricate two different kinds of one-dimentional nanomaterials by electrospinning followed by calcination process. The structure and morphology of the obtained samples were characterized by thermogravimetric analysis (TG), field emission scanning electron microscopy (FE-SEM), fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The photoluminescence (PL) spectroscopy was employed to study their luminescent properties. The results indicated that Y2O3:Eu3+ nanobelts were obtained by using of de-ionized H2O as the solvent, but the obtained Y2O3:Eu3+ nanofibers with solvent of DMF. Y2O3:Eu3+ samples had crystallized at 800 oC with the cubic phase. Furthermore, the PL emission intensity of Y2O3:Eu3+ nanofibers are about two time higher than those of nanobelts .

Key words: Y2O3:Eu3+, electrospinning, nanobelts, nanobelts
