From hollow gold nanoparticles to gold nanorings: Morphological tunability of the plasmonic response

Martin Prieto, Raul Arenal, Luc Henrard +3

The optical and morphological properties of hollow gold nanoparticles (HGNPs) can be finely modified by employing Poly-L-Lysine hydrobromide (PLL), an homo poly aminoacid of the L-…
