Abstract

Abstract: Recently, emergent luminescent fibers have attracted extensive attention due to their intriguing applications. However, developments of the luminescent fibers are severely limited by their high‐cost and low efficient manufacturing protocols including in situ growth, dry‐wet spinning, co‐electrospinning, and multistep dip‐coating. Herein, a cost‐efficient and large‐scalable approach (namely, one‐step dip‐coating) is proposed. In this work, the photoluminescent fibers/yarns are fabricated by one‐step dipping of pristine fibers/yarns in dispersions of hybrid dots (silicon/carbon). Subsequently, Janus fabrics with striking photoluminescent patterns are developed by weaving, knitting, and braiding, respectively. An innovative anticounterfeiting technique is further developed by combing the merits of the photoluminescent fibers/yarns with textile weaving methods. The designed photoluminescent patterns can endow the weaving fabrics with excellent concealment performance. As far as it is well known, it is the first time to achieve asymmetric photoluminescent patterns on two sides of the woven fabrics by this innovative technology. Additionally, the fabrics treated with hybrid dots exhibit excellent antibacterial ability against both Staphylococcus aureus and Escherichia coli . These findings can not only provide an unprecedented insight for realizing high‐level anticounterfeiting applications, but also guide to exploit versatile applications in medical care, fashion design, stage performances, trademark, and confidential documents in the future.
