Abstract

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