title: Fabrication of silica nano/micro-fibers doped with one-dimensional assembly of silver nanoparticles.
abstract: Nano/micro fibers doped with metal nanocrystals are of great interest both theorectically and practically. Nevertheless, the ordered assembly of metal nanocrystals with desired patterns in nano/micro fibers still remains a big challenge, which constrains the further development of the performance of the material. In this investigation, we propose a facile strategy based on the sol-gel and coaxial electrospinning technique to fabricate silica submicron fibers incorporating ordered 1D array of silver nanoparticles. The silver nanoparticles align strictly in a head-to-tail manner in silica fibers, and their size, shape and population are conveniently controlled through tailoring the properties of the precursor solutions and the electrospinning parameters. Therefore, the plasmon property of the obtained fibers is tuned with great freedom. The fabrication method applied here holds great potential for low-cost preparation of metal/glass composite fibers for nano/micro optical applications in general.
