Localized surface plasmon resonance (LSPR) has many applications which require meeting specific wavelength windows. The most prominent examples are photothermal therapy in biology, matched to the biological window (650–1350 nm), and communication relying on photodetection optoelectronics, (1260–1675 nm). However, for classic noble metals (Au, Ag), tuning LSPRs from visible region these two windows is still a demanding task due their intrinsic limitations charge density dielectric function....
