Abstract

We prepare metallic tungsten oxide(WO3-x) nanoparticles by RF sputtering without doping, and investigate optical properties of the nanoparticles. Optical absorption spectra show clear two independent absorption species in near-infrared region, which are originated from localized surface plasmon resonance and polaron. This concurrent activation property not only provides a stage for understanding the fundamental physics of plasmon and polaron of tungsten oxide nanoparticles, but also shows that the nanoparticles are interesting candidates for device application.
