Electrospinning Fabrication and Upconversion Luminescent Properties of CaTiO3: Er3+ Microbelts
Abstract:
One-dimensional CaTiO3:Er3+ microbelts have been prepared by electrospinning method.X-ray diffraction,Fourier transform infrared spectroscopy,Raman spectroscopy,scanning electron microscopy(SEM),transmission electron microscopy(TEM),high-resolution transmission electron microscopy(HRTEM),up-converted luminescence were used to characterize the resulting samples.SEM and TEM analysis indicate that the obtained precursor belts have a uniform size,and the as-formed microbelts consist of nanoparticles.Under 980 nm laser beam excitation,the CaTiO3:Er3+ samples exhibit a green emission band with a maximum at 546 nm originating from the 4S3/2→4I15/2 transitions of Er3+ ions.When the Er3+ concentration increases,the red emission of CaTiO3:Er3+ increases relative to the green emission,which is due to the energy transfer between Er3+ ions.
