Color-tunable flexible composite nanofibers containing Dy(BA)(3)phen and Eu(BA)(3)phen complexes have been successfully fabricated via a facile electrospinning process. Scanning electron microscopy, energy dispersive spectrometry and fluorescence spectroscopy were used to characterize the samples. The diameter of the composite nanofibers is 420.83 +/- 6.55 nm. Tunable color from greenish blue to white to orange can be realized in a single flexible composite nanofiber by varying the mass ratio of Dy(BA)(3)phen-Eu(BA)(3)phen, and it is the first time to obtain white-light-emitting flexible nanofibers using rare earth complexes as luminescent centers. In particular, the composite nanofibers can respectively emit cool and warm white light with certain doping contents of Dy(BA)(3)phen and Eu(BA)(3)phen. The novel color-tunable composite nanofibers have potential applications in the fields of fluorescent lamps, field emission displays and color displays.
