Plasmonic behaviour and plasmon-induced charge separation of nanostructured MoO3-x under near infrared irradiation

Abstract

Plasmon-induced charge separation (PICS) allows direct conversion of localized surface plasmon resonance (LSPR) to electron flows and photoelectrochemical reactions. However, PICS has been achieved only by plasmonic noble metal nanoparticles, not with compound nanoparticles. In order to achieve compound PICS, we prepared MoO3-x nanostructures that exhibit LSPR in the near infrared region by using metal oxide or metal nanoparticles as templates. We developed solid-state cells based on the MoO3-x nanostructure. Their photoresponses to 700–1400 nm infrared light were investigated and analyzed on the basis of PICS mechanisms.
