Microstructures of ZnO Electrospun Nanofibers on AZO Glass

Abstract:

ZnO electrospun nanofibers were considered to be potential novel materials in applications of photovoltaic devices and sensors. AZO glass was usually used in those devices as transparent electrodes. ZnO nanofibers on AZO glass were synthesized by electrospinning and calcination process. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), Raman spectroscopy and photoluminescence (PL) spectrum was employed to investigate the morphology, structure and optical performance of ZnO nanofibers. Network structure composed of sheet ZnO was observed. Raman spectra and PL spectrum indicated the existence of defect states in the ZnO nanofibers.
