| Summary: | Silver nanowires (AgNWs) have received considerable attention from both academia and industry due to their exceptional potential applications in various electronic devices. In this work, pure AgNWs in the absence of nanoparticles are synthesised through chemical reduction method at low temperature 80 °C. AgNWs are produced via a reducing agent of tannic acid and a capping agent of polyvinylpyrrolidone (MW ≈ 1,200,000). The purity of the as-prepared AgNWs is improved in the presence of both chemical reactants. The controllable morphologies and sizes make the AgNWs grown steadily up to ~30 μm in length with ~50 nm in diameter. To enhance the yield of AgNWs, variations in the concentrations of silver nitrate precursor (AgNO3) in the synthesis of AgNWs are highlighted. The properties of the synthesised AgNWs are characterised by scanning electron microscopy (SEM), UV-visible absorption spectroscopy, and photoluminescence spectroscopy. The overall properties of the AgNWs in terms of intensity of scattered light and the optical transmittance were largely improved as compared to other reported studies. |
