Electrospinning Construction of Flexible Composite Nanoribbons with Color-Tunable Fluorescence

摘要： Herein, we describe the innovative one-dimensional nanomaterials, electrospun composite nanoribbons (width 10.119 ± 0.186 μm) containing complexes of Eu(TTA)3(TPPO)2 and Tb(BA)3phen in a matrix of polymethylmethacrylate (PMMA). Scanning electron microscopy (SEM), energy dispersive spectrometry (EDS) and fluorescence spectroscopy were used to characterize the final products. The novel luminescent composite nanoribbons exhibit green, orange and red fluorescence emission peaks at 490, 545, 592, and 615 nm, which are ascribed to the 5D4 → 7F6 (490 nm) and 5D4 → 7F5 (545 nm) energy transitions of Tb3+ ions, and the 5D0 → 7F1 (592 nm), 5D0 → 7F2 (615 nm) transitions of Eu3+ ions, respectively. It is observed that the doping percentage and the chosen excitation wavelength could be used to tune the emission color of the samples. The color-tunable luminescent composite nanoribbons have potential applications in the fields of display panels, lasers and bioimaging.
