    Project supported by the National Natural Science Foundation of China (Nos. 50972020, 51072026), Ph.D. Programs Foundation of the Ministry of Education of China (Nos. 20102216110002, 20112216120003), the Science and Technology Development Planning Project of Jilin Province (Nos. 20070402, 20060504), Key Research Project of Science and Technology of Ministry of Education of China (No. 207026).

A new kind of luminescence-electricity bifunctional Tb(BA)3phen/PANI/PVP composite nanofibers was fabricated through doping of polyaniline (PANI) and terbium complex [Tb(BA)3phen] in polyvinyl pyrrolidone (PVP) via electrospinning. Scanning electron microscope (SEM), energy dispersive spectrometer (EDS), fluorescence spectrometer and broadband dielectric spectrometer were used to characterize the samples. The results indicated that the average diameter of the Tb(BA)3phen/PANI/PVP composite nanofibers was ca. (331±43) nm. Under the excitation of 276 nm ultraviolet, Tb(BA)3phen/PANI/PVP composite nanofibers emitted the predominant emission peaks at 491, 547 and 585 nm, corresponding to 5D47F6, 5D47F5 and 5D47F4 transitions of Tb3+, respectively. The strongest emission intensity was acquired when the mass ratios of Tb(BA)3phen, PANI and PVP was 15:10:100. The electric conductivity of the composite nanofibers was increased with the increase of PANI content, and reached 1.531×10-6 S/cm in high frequency electric field (106 Hz) when the mass ratio of PANI to PVP was 50%. The luminescent intensity and electric conductivity of Tb(BA)3phen/ PANI/PVP composite nanofibers can be tuned via adding of various amounts of Tb(BA)3phen and PANI into the composite nanofibers. This preparative technique is of universal significance and can be used to fabricate other similar bifunctional luminescence-electricity composite nanofibers. This new type bifunctional luminescence-electricity composite nanofibers will have wide applications in many fields due to their excellent fluorescence and conductivity.
