This study developed novel fluorescent nanofibers via electrospinning of chromophore-doped cellulose, using cellulose as the host material and perylene dye derivatives as active dopants. The fabricated fluorescent cellulose nanofibers pave the way for the development of promising textile fluorescence materials for applications such as flexible displays, photonics, and optical devices.
Novel fluorescent nanofibres were developed via the electrospinning of chromophore-doped cellulose. Two different perylene-doped cellulose fluorescent fibres were fabricated using cellulose as a host material and perylene dye derivatives as active dopants. Fluorescent cellulose nanofibres were prepared via the electrospinning technique using two different perylene dyes, including perylene diimide and perylene mono-imide sodium/potassium salts. The generated fluorescent silica nanoparticles exhibited diameters varying in the range 80-180 nm. The generated electrospun fluorescent nanofibrous structures displayed smooth surfaces with average diameters of 200-300 nm for cellulose comprising perylene diimide and sodium/potassium salts of perylene mono-imide dyes, respectively, dispersed uniformly in the cellulose matrix. The generated fluorescent nanoparticles and nanofibres were characterized by different standard methods, including scanning electron microscopy (SEM), transmission electron microscopy (TEM), fluorescent optical microscope (FOM) and Fourier-transform infrared spectra (FT-IR). The fluorescence properties of the fabricated cellulose nanofibres were explored. Those fluorescent nanofibres pave the way for the development of promising textile fluorescence materials, such as flexible displays, photonics, and optical devices.
