纳微米醋酸纤维素多孔发光纤维的制备及其荧光性能
Preparation and fluorescence properties of nano-micron cellulose acetate luminescence fiber with porous structure
摘要
Abstract
In order to prepare the rare earth luminescence fibers with high and persistent fluorescence intensity and high fluorescence lifetime, the nano-micron rare earth luminescence fibers with porous structure and with smooth surface were prepared by electrospun technique and using cellulose acetate (CA) and rare earth luminescent materials of p-toluic acid as raw materials. The composition structure, apparent morphology, fluorescence characteristics of the prepared sample were characterized by field emission scanning electron microscope, fluorescence spectrometer, Fourier-transform infrared spectrometer, transmission electron microscope and energy spectrum analyzer. The results show that the rare earth luminescent materials of p-toluic acid are distributed uniformly in the nano-micron CA fiber, which entrusted the fibers durable fluorescence property;the porous structure improves the fluorescence intensity of the nano-micron CA rare earth luminescence fiber, and the fluorescence intensity and the fluorescence lifetime are 3.50 times and 1.59 times that of the CA rare earth luminescence fibers with smooth surface, respectively.关键词
