摘要/Abstract

摘要： 采用高温固相法制备了Sr2MgSi207：Eu2+，Dy3+长余辉发光材料，并通过熔融纺丝制备出含有该发光材料的聚丙烯夜光纤维；对该夜光纤维的微观形貌、物相结构、光谱特征及余辉性能进行了测试和表征分析，结果显示，该纤维具有Sr2MgSi207：Eu2+，Dy3+发光材料和聚丙烯基材两者独立叠加的物相特征，激发光范围为250～450nm，能发出波长460nm的蓝色余辉，余辉初始强度大于600mcd/m2，寿命达7h，余辉衰减过程由快、慢两个阶段组成。

Abstract: The long afterglow phosphor of Sr2MgSi2O7: Eu2+, Dy3+ was synthesized by high temperature solid state method. Polypropylene luminescent fiber containing this phosphor was prepared by melt spinning method. Micro morphology, phase structure, spectral features and afterglow properties of the luminescent fiber were tested and analyzed. The results show that the fiber has independent superposition phase features of both Sr2MgSi2O7: Eu2+, Dy3+ and polypropylene; the range of its excitation light locates among 250～450nm; it can emit blue light of 460nm wave length; its initial luminescent intensity is more than 600mcd/m2, and afterglow time lasts 7h; the process of afterglow decay consists of fast stage and slow stage.

Key words: luminescent fiber, rare earth luminescent materials, Sr2MgSi2O7, long afterglow
