Abstract Fiber‐based thermoelectric (TE) device that can collect waste heat of human body and convert it into electricity is growing fast great significance for sustainable development. Although ionic (i‐TE) ionogels are considered to be the next generation TE materials, construct ionogel fiber with synergistically enhanced mechanical i‐TE performances remains big challenge. Herein, poly(vinylidene fluoride‐co‐hexafluoropropylene)/1‐ethyl‐3‐methylimidazolium dicyanamide/ethanol/NaTFSI/SiO 2 (PH/ED‐E‐Na‐SiO ) ultrahigh Seebeck coefficient 47.5 mV K −1 conductivity 43.7 mS cm constructed by a proposed antisolvent‐doping‐hybrid synergistic strategy. The mainly attributed low crystalline structure improvement in ions dissociation, migration, diffusion difference. corresponding power factor PH/ED‐E‐Na‐SiO film as high 9845.8 µW m −2 , which almost highest value ever reported. Based on this, comparable significantly tensile strength strain (from 327 KPa 47% 17.7 MPa 70% fiber) prepared simple coating process. It weaved wearable generates thermovoltage lights light‐emitting diode (LED) bulb, demonstrating its application potential energy supply device.

Abstract Driven by the escalating demand for cutting‐edge materials in interactive encryption and customized display, optimization of excitonic coupling mechanisms perovskite‐based luminescent systems has emerged as a pivotal focus advanced research. Inspired synergistic doping (SD), photoswitchable energy transfer channel is realized utilizing UV‐responsive Cs 2 NaInCl 6 : Sb 3+ ‐Ho (CNIC: Sb‐Ho) phosphor. Benefiting from self‐trapped exciton , visible blue luminescence Ho achieves excitation reconstruction through SD, with sensitization coefficient to CNIC reaching two orders magnitude. Notably, CNIC: Sb‐Ho quantum dot embedded into polyacrylonitrile (PAN) polymethyl methacrylate (PMMA) fibers, respectively, distinct color coordinate channels are created altering concentration fiber matrix, thereby enabling personalization customization desired colors enhanced precision. Furthermore, excellent read‐in performance under UV irradiation achieved screen‐printing microcrystal on nanofibers combining it ACSII code, which endows UV‐induced controllable shape programming behavior multidimensional information encryption. This work establishes an visual interaction framework effectively integrating perovskite fluorescence tunability nanofiber adaptive structures, thus opening new possibilities smart application next‐generation optical technology.

In the research of modern photoelectric materials, high temperature resistant luminous fibers with long duration and excellent sewing properties have attracted interest researchers. Here, we introduce a continuous manufacturing strategy based on microfluidic wet-spinning technology for preparation persistent luminescent fibers. Luminescent can continuously glow 3 h, quantum yield is as 42.8%, they luminescence intensity at ambient temperatures 50-200 °C. At same time, limiting oxygen index fiber close to 30%, indicating flame retardancy. addition, also has tensile strength 18.9 MPa good sewability. Overall, this simple processing provides potential solution practical application wearable or fabrics in field fire rescue.

Perovskite quantum dots (PQDs) have attracted emerging attention as fluorescent and light-absorbing materials for next-generation optoelectronics due to their outstanding properties cost-efficiency. However, PQD thin film suffers significant instability structure material failures, which hinders application in flexible reliable PQD-based advanced wearable devices. Herein, we use commercial cellulose fiber-based filter paper a substrate synthesize PQDs situ fabricate PQD-paper free-standing composite film. The abundant hydroxy capping ligands of fibers the unique dense network can facilitate confined crystallization, forming strong interactions between substrate, unpackaged showed extraordinary stability (>30 days) air with high humidity (90%). Meanwhile, interaction enables an ultrasimple drop-cast synthesis process excellent tolerance, making it customizable easy scale up (10 cm diameter). Due uniformly dispersed on demonstrates impressive photo-responsive properties. Photodetector (PD) arrays were designed graphitic electrodes, circuits fabricated by drawing.
