Abstract

A luminous polypropylene/SrAl2O4: Eu2+, Dy3+ fiber was prepared by the way of melt-spinning method which uses triarylsulfonium hexafluoroantimonate (TSHF), organic silicon-modified luminescent materials and polypropylene substrate to produce a new luminous material with blue-light emission in the darkness. The effect of TSHF on emission luminescence properties was studied by analyzing the afterglow brightness, emission spectral and colorimetric characteristics. The results indicate that the spectral characteristics of the fiber were mainly determined by the energy transfer from TSHF to SrAl2O4: Eu2+, Dy3+ powder. When the doping amount of TSHF reached 0.5 wt%, the emission wavelength of the fiber began to shift toward the blue region..
