doi: 10.1021/jp062536y. The plasmon resonance appears in the narrow spectral region of the spectrum, especially for the silver nanostructures (Yaremchuk et al. 2014; Yaremchuk et al. 2002).The nature of the resonance A key parameter for optimizing nanosized optical devices involving small metal particles is the spectral width of their localized surface plasmon resonances (LSPR), which is intrinsically limited by the confinement-induced broadening (quantum finite size effects).
