Figure 3From: Tunable surface plasmon resonance frequencies of monodisperse indium tin oxide nanoparticles by controlling composition, size, and morphologyNormalized UV–vis-NIR spectra of ITO NPs with different doping concentrations of Sn (hot-injection approach). The SPR peak wavelengths of 6%, 7.6%, 10%, 12%, and 30% Sn-doped ITO NPs are 1,826, 1,774, 1,600, 1,678, and 1,993 nm, respectively.Back to article page
