FIG. 1.

SEM images of PVA∕ZnO hybrid fibers with average diameter about . (scale ).

FIG. 2.

IR spectra of PVA (a) and PVA∕ZnO (b) hybrid fibers. The arrow indicated the vibration band of Zn–O.

Image of FIG. 3.
FIG. 3.

Resonant Raman spectra of PVA∕ZnO hybrid fibers at room temperature using line of a He–Cd laser as the excitation source. This band, centered at , was attributed to the Raman -LO phonon scattering of ZnO.

FIG. 4.

DSC curves of PVA (a) and PVA∕ZnO (b) fibers, showing that PVA was stabilized by ZnO until heating to .

FIG. 5.

PL spectra of ZnO QDs (a), PVA fibers (b), PVA∕ZnO spin cast film (c) and PVA∕ZnO hybrid fibers (d) at room temperature using the line of a He–Cd laser as the excitation source. Insert is the luminescence photograph of the PVA∕ZnO hybrid fibers taken by using UV filter and charge coupled device camera (color online).
