Recent Advances in the Design, Synthesis, and Wearable Applications of Luminescent Fibers and Textiles

• • Spinning chemistry enables the synthesis of ultra-stable CsPbX3 (X = Cl, Br, I) perovskite luminescent filaments with a high photoluminescence quantum yield (PLQY) of 24.5% and a high stretchability of ~2400%, addressing the stability and flexibility bottlenecks for wearable applications. • • The review cites a self-healing actuatable electroluminescent fiber (Fu et al., Nat Commun, 2024) that demonstrates the potential for multifunctional fibers, though specific metrics are not detailed; this highlights the need for quantitative comparisons in future work. • • Lead-free double perovskites with near-unity photoluminescence quantum yield (approaching 100%) have been developed for flexible anti-counterfeiting fibers and optoelectronic devices (Nie et al., Chem Eng J, 2025), offering a safer alternative to lead-based perovskites. • • Organic polymorphic crystals with multi-stimuli response, including excellent mechanical elasticity and novel two-stage heterotropic photochromism, have been reported (Yao et al., Sci China Mater, 2024), indicating potential for multifunctional luminescent fibers with tunable properties.
