Preparation and Luminescence Properties of Rare Earth Magnesium Strontium Silicate Luminescent Fiber

Abstract:

The polypropylene luminescent fiber containing Sr₂MgSi₂O₇: Eu²⁺, Dy³⁺ phosphors was prepared by melt-spinning method. Crystal 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 wavelength locates among 250~450 nm; it can emit blue light of 460 nm wavelength; its initial luminescent intensity is more than 600 mcd/m², and afterglow time lasts 7 h; the process of afterglow decay consists of fast stage and slow stage.
