Whispering-gallery-mode full-color laser textiles and their anticounterfeiting applications

Abstract Light-emitting fabric can facilitate the innovation of wearable display applications. Electronic and luminescent textiles capable communicating, sensing, supplying energy have been achieved. However, a facile strategy for fabricating large-area flexible lasing has not yet reported. In this work, we propose gravity-assisted rotatory drawing method microfibers, which be woven into multicolor textiles. By regulating doped dyes solution viscosity, achieve mass manufacturing microfibers with different emission colors modes further weave them full-color wide color gamut, approximately 79.1% larger than that standard RGB space. For application, print nanoparticle patterns on textile encode it programmable signal distribution, supply an anticounterfeiting label efficient authentication. This work unifies fabrication application textiles, expect will provide new platform devices.
