外文摘要：The increasing demand for luminescent fibers capable of responding to diverse environmental conditions by modulating their emission is evident, particularly for applications in smart textiles and wearable sensors. Nevertheless, the majority of luminescent fibers are constrained to reacting to a singular stimulus, resulting in static emission. Consequently, an urgent requirement arises for fiber-based wearable sensors endowed with the capability to undergo luminescent color transformations, particularly in applications requiring on-demand color changes. In the present investigation, we proficiently synthesized two variants of rare-earth-doped phosphors: Y2O2S: Eu3+, Mg2+, Ti4+ (YOS) exhibiting prolonged persistent luminescence and BaMgAl10O17: Eu2+ (BMA) manifesting phosphorescence. Through straightforward blending of YOS and BMA in predefined proportions, a modifiable emission color system can be achieved. By integrating YOS and BMA, each exhibiting distinct afterglow characteristics such as enduring red luminescence and blue phosphorescence, into a polydimethylsiloxane (PDMS) matrix, we crafted innovative stretchable UV-sensing composite fibers capable of modifying their luminescent color through the wet-spinning process. The as-prepared fibers demonstrate the capability to transition between two discernible luminescent colors in reaction to UV irradiation. Moreover, the as-prepared fiber exhibits exceptional tensile properties, rendering them suitable for deployment in aesthetic displays, anti-counterfeiting measures, and smart wearable textiles.
