摘要：

针对稀土铝酸锶夜光纤维发光颜色单一的问题,采用微波煅烧法将具有共轭结构的光引发材料三芳基硫鎓六氟锑酸盐(THFS)和稀土激活的碱土铝酸锶发光材料相结合,以聚丙烯为基材通过熔融共混纺丝法制备出受光激发后在黑暗处可发出蓝色光的功能纤维, 探讨原料配比、熔融温度、激发条件等对纤维光谱特性的影响。结果表明:当THFS质量分数大于0.5%时,纤维的发射光谱开始向短波方向移动,光谱产生蓝移;发光材料质量分数的改变没有对纤维的发射峰造成影响,光谱蓝移效果不明显;随着激发波长的减弱,纤维的发射波长向短波长方向移动,发射峰发生蓝移。

Abstract:

In order to solve single-light color for the rare-earth strontium aluminate luminescent fiber, the blue-light luminesent fiber doped with organic onium salt was prepared by combining photo-initiating material triaryl sulfonium hexafluoroantimonate (THFS) and rare earth-activated alkaline earth strontium aluminate luminescent materials by microwave calcination, and melt blend spinning using PP as matrix. Moreover, the influence of the ratio of the raw materials, melting temperature, excitation conditions and other factors on the spectral performance of the fiber was investigated. The results show that when the content of THFS reaches 0.5%, the emission spectrum moves toward the shortwave and the spectrum shifts blue. The change of the luminescent material has no effect on the emission peak of the luminescent fiber, and the effect of light blue shift is not obvious. As the excitation wavelength is weakened, the emission wavelength of the luminescent fiber moves toward the short wavelength, and its emission peak produces blue shift.

Key words: luminescent fiber, triarylsulfonium bexafluoroantimonate, rare-earth strontium aluminate luminescent material, emission spectrum, blue shift
