力致/光致复合纱线的多级发光性能研究
Research on multi-level luminescence performance of mecha-noluminescent/photoluminescent composite yarns
摘要
Abstract
To explore the mechanism underlying the mechanoluminescence/photoluminescence multi-stage lumines-cence effect,this study used spandex as the substrate and coated its surface with a luminescent layer containing ZnS:Cu and SrAl2O4:Eu2+,Dy3+(SAOED)particles,thereby preparing core-shell structured composite yarns.Systematic charac-terizations were conducted on the morphology and mechanical properties of the yarns,along with measurements of key parameters including light absorption characteristics and luminescence intensity.Furthermore,the potential application of the composite yarns in embroidery technology was explored.Experimental results demonstrated that the luminescent particles were uniformly distributed in the coating layer.The composite yarns exhibited excellent flexibility with a break-ing elongation as high as 800%.Under excitation by 365 nm ultraviolet light,the yarns emitted green light at 500 nm with a persistent luminescence duration of over 1.5 hours.When mechanical force was applied,the luminescence gener-ated by ZnS:Cu could be efficiently absorbed by SAOED and trigger secondary excitation,leading to enhanced lumines-cence and thus realizing the multi-stage luminescence effect.This material integrates dual-responsive properties of photo-luminescence and mechanoluminescence.Embroidery application showed that the yarns could form luminescent pat-terns with clear contours.This special luminescent yarn provides a novel functional material for the development of emergency rescue equipment and nighttime safety warning textiles.关键词
