Eu(III) complex/polymer composite nanofibers were prepared by electrospinning and showed strong oxygen dependent characteristics. The oxygen-sensing properties of the composite nanofibers with different loading levels of Eu(III) complex were compared.
Eu(III) complex/polymer composite nanofibers of poly(vinylpyrmlidone) (PVP) and europium complex Eu(N-DIIQ)(TTA)(3) (N-DPIQ = N-ethyl-dipyrido [f,h] indolo [3,2-b] quinoxaline, TTA = 2-thenoyltrifluomacetonate) are prepared by electrospinning. The composite nanofibers are characterized by Scanning Electron Microscope (SEM), Infrared absorption spectra (IR), and luminescence intensity quenching upon various oxygen concentrations. It is observed that the Eu(III) complex/polymer composite nanofibers exhibit a strong oxygen dependent characteristic. The oxygen-sensing properties of the composite nanofibers with different loading levels of Eu(III) complex are compared.
