Structural and Photoluminescence Characteristics of ZnTiO3:Pb2+ Nanofibers Produced by Electrospinning
Through sol-gel processing and electrospinning technique,ultrathin fibers of PVP/ ZnTiO3:Pb2+ composites were prepared.After calcined of the above precursor fibers at 600℃,the spinel ZnTiO3:Pb2+ nanofibers,with a diameter of 100-200nm,were successfully obtained.The nanofibers were characterized by scanning electron microscopy (SEM),fourier transform infrared (FT-IR),X-ray diffraction (XRD) and photoluminescence (PL).The results showed that the crystalline phase and morphology of the fibers were largely influenced by the calcination temperature.The PL spectra of the samples measured at different excitation wavelength reveal a novel luminescent phenomenon in blue and green region,which can be attributed to the Pb2+-related charge-transfer transitions in ZnTiO3 nanofibers.
