Inorganic CsPbX3 (X = Cl, Br, I) perovskite quantum dots (PQDs) have attracted widespread attention due to their excellent optical properties and extensive application prospects. However, inherent structural instability significantly hinders practical despite outstanding performance. To enhance stability, an in situ electrospinning strategy was used synthesize CsPbX3/polyacrylonitrile composite nanofibers. By optimizing process parameters (e.g., halide ratio, voltage, heat treatment temperature), all-inorganic PQDs been successfully grown a polyacrylonitrile (PAN) matrix. During the process, rapid solidification of electrospun fibers not only effectively constrained formation large-sized but also provided effective physical protection for PQDs, resulting improvement water stability by minimizing external environmental interference. Even after storage over 100 days, maintained approximately 93.5% photoluminescence intensity. Through adjustment halogen elements, as-obtained nanofibers exhibited color-tunable luminescence visible light region, based on this, series multicolor anti-counterfeiting patterns were fabricated. Additionally, benefiting from performance, CsPbBr3/PAN film combined with red-emitting K2SiF6:Mn4+ (KSF) blue LED (460 nm), producing stable efficient WLED device color temperature around 6000 K CIE coordinates (0.318, 0.322). These results provide general approach synthesizing PQDs/polymer nanocomposites emission, thereby promoting applications multifunctional optoelectronic devices advanced anti-counterfeiting.
