Abstract
Titania (TiO2)/PVP composite nanofibers were prepared with electrospinning method followed by calcining in air at different temperatures. The nanofibers were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), Raman spectrum and photoluminescence (PL) spectrum. The results showed that the nanofibers are uniform and have an average diameter of â¼40Â nm. It is also found that the photoluminescence properties were largely influenced by different crystalline structure. The nanofibers yield visible photoluminescence peaking at 550Â nm for anatase phase and near infrared photoluminescence peaking at 820Â nm for rutile phase.
