- Abstract
Luminescence nanofibers have been widely used in trademarking, anticounterfeiting materials and personalized clothing. However, current luminescent nanofibers, which are generally based on luminescent dyes or rare earth metal ions, reveal limited stability and adjustability thereby significantly hindering their potential industrial applications. Inspired by the CuI-based luminescent materials, a series of eco-friendly, low-cost, and color-tunable luminescent one dimensional (1D) materials based on biomass material, cellulose acetate (CA) supported CuI-based luminescent complexes hybrid nanofibers (CuI-LC@CA) were designed and prepared by electrospinning process. The structure and surface morphology of CuI-LC@CA nanofibers were characterized by SEM, XPS, PXRD, TGA, as well as FT-IR. Exploration of their luminescent properties reveals that CuI-LC@CA nanofibers exhibit excellent luminescent performance, and their emission colours are adjustable by modifying organic ligands of CuI-LC. Remarkably, CuI-LC@CA nanofibers showed excellent photostability, which retained more than 80% intensity after UV lighting for 48 h. Our work provides a feasible solution for the functional design of CuI-LC based luminescent nanofibers. The versatility of its structural design can contribute to a new system for building functional devices.
