Organic onium salt has been used as a photosensitive pigment for rare-earth luminescent fibre. A certain dose of organic onium salt has been added to rare-earth strontium aluminate luminescent fibre (RESALF) during its melt spinning. It’s photochromatic property is studied by comparing RESALFs with and without the organic onium salt. RESALF photochromatic identification method is devised according to the Standard Colorimetric System CIE (International Commission on illumination) 1931 XYZ. The results show that, when excited by 365nm wavelength light, RESALF doped with organic onium salt exhibits good photochromatic properties. The luminescence color of RESALF doped with organic onium salt switches from the yellow-green region to the blue region. The light-chromatic recognition method used is thus able to provide an accurate identification of the luminescence color of the new RESALF.

掺有机鎓盐的稀土发光纤维的光色识别

有机鎓盐已经用作稀土发光纤维的光敏颜料。在熔融纺丝过程中，已将一定剂量的有机鎓盐添加到稀土铝酸锶发光纤维（RESALF）中。通过比较带有或不带有有机鎓盐的RESALF来研究其光致变色性质。RESALF光色识别方法是根据标准比色系统CIE（国际照明委员会）1931 XYZ设计的。结果表明，当被365nm波长的光激发时，掺有有机鎓盐的RESALF具有良好的光致变色性能。掺杂有有机鎓盐的RESALF的发光颜色从黄绿色区域变为蓝色区域。
