Photoluminescence properties of the rare-earth ions in the TiO{sub 2} host nanofibers prepared via electrospinning
- Alan G. MacDiarmid Institute, Jilin University, Changchun 130012 (China)
Luminescent rare-earth (RE) ions doped TiO{sub 2} nanofibers have been prepared by electrospinning of a mixture solution of rare-earth acetylacetone (RE(C{sub 5}H{sub 7}O{sub 2}){sub 3})/titanium tetraisopropoxide (Ti (OiPr){sub 4})/poly(vinyl pyrrolidone) (PVP) (RE = Eu, Er, Ce, Pr), followed by calcination at high temperature. Scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) analyses demonstrated the morphology and the structure of the rare-earth doped TiO{sub 2} nanofibers. Exciting the nanofibers results in an energy transfer from surface states of TiO{sub 2} to that of the rare-earth ions and the photoluminescence is observed from the crystal field states of the rare-earth ions.
