Abstract
The localized surface plasmon resonance (LSPR) of Ag/indium tin oxide (ITO)@polystyrene (PS) in the visible-NIR region was dependent on the tuning of the carrier density caused by adjusting the thickness of the ITO layer. The two-dimensional correlation spectroscopy (2D-COS) results of the dependence of each component in the UV-vis-NIR spectrum on the carrier density response enabled the successful exploration of the carrier transport process.
