Plasmonic Behaviour of Phenylenediamine Functionalised Silver Nanoparticles

The surface functionalisation of AgNPs has demonstrated improved capability for various applications by modifying their surface chemical conditions. In this study, AgNPs functionalised with p-phenylenediamine (PPD) ligand were prepared, and the plasmonic effects of the nanocomposites were then inves...
