| Research Abstract |
Here we report the synthesis of conducting indium tin oxide (ITO) nanoparticles (NPs) and their SPR properties, where SPR peaks of the ITO NPs can be easily tuned by changing the concentration of Sn doping from 3 to 30 mol %. The shortest SPR wavelength of 1618 nm in 10 %Sn-doped ITO NPs may reflect the highest electron carrier density in the ITO NPs and represents the first example of well-defined SPR tunable conductive metal oxide NPs in the NIR region. The controllable SPR frequencies of metal oxides may offer a novel approach for noble metal-free SPR applications.
