静电纺丝是一种简单并有效制备连续纳米纤维的手段。 作者利用平行电极法成功制备了有序排列的MEH-PPV/PVP静电纺丝纳米纤维, 并用超快光谱的方法进行研究。 激发光和荧光的方向分别沿着纤维轴的轴向和径向。 径向发射的荧光稳态荧光光谱比轴向发射的荧光蓝移, 说明径向的聚合度比轴向较低。 有序纤维荧光在所有荧光波长范围内, 径向发射荧光的激子迁移速度快于轴向发射荧光的激子迁移速度。

Electrospinning is a simple and effect technology which can produce continuous nanofibers. We get aligned electrospun nanofibers successfully by using parallel electrodes. We report our studies on transient fluorescence of aligned electrospun fibers. The fibers are excited and their fluorescences are observed both at axial and radial polarization. Steady-state PL spectra shows radial emission blue-shift more than axial!emission, due to weakened aggregation of molecular chains in radial direction. At all emission wavelength, radial emission excitons migrate faster than axial emission excitons.
