摘　　要：为了实现稀土硅酸镁锶发光纤维的荧光颜色的蓝移,研究了基于光谱叠加原理,选用发射波长为438 nm的深蓝色光谱调节剂与稀土硅酸镁锶长余辉发光材料共混,制备了PET长余辉发光纤维。对纤维的形貌结构、荧光光谱、发光颜色、余辉以及力学性能进行了系统的研究。结果表明,光谱调节剂能够促进发光纤维发射光谱的蓝移,当稀土硅酸镁锶长余辉发光材料与光谱调节剂质量比4∶6时,发光纤维的发射峰由470蓝移至458 nm,荧光颜色由天蓝色变为蓝色。尽管光谱调节剂的加入会对余辉亮度和余辉寿命造成一定的负面影响,但会显著提升发光纤维的手感及力学性能。研究结果为促进稀土硅酸镁锶发光纤维在治疗新生儿黄疸症状上的应用奠定了理论基础。In order to promote the fluorescence color blue shift of the rare earth doped strontium magnesium silicate luminous fiber,the dark blue spectrum regulator with emission wavelength of 438 nm was blended with rare earth strontium magnesium silicate long afterglow luminescent material to prepare PET long afterglow luminous fiber on the basis on the principle of spectral superposition.The morphology,structure,emission spectrum,fluorescence color,afterglow and mechanical properties of the fibers were systematically studied.The results showed that the spectral regulator could promote the emission spectrum blue shift of the luminous fiber.When the mass ratio of the rare earth strontium magnesium silicate long afterglow luminescent material to the spectral regulator was regulated to 4∶6,the emission peak of the luminous fiber would blue-shift from 470 nm to 458 nm,and the fluorescence color changed from sky blue to blue.Although the addition of spectral regulator had a certain negative impact on the afterglow brightness and afterglow lifetime,it could significantly improve the hand and mechanical properties of the luminous fibers.These results laid a theoretical foundation for promoting the application of the rare earth magnesium strontium silicate luminescent fiber in the treatment of neonatal jaundice symptoms.
