- Description
- The sodium tungsten bronzes (Nax WO3) are vividly coloured metallic materials where the optical behaviour can be attributed to the bulk plasma frequency occurring in the visible part of the spectrum. A combination of density functional theory (DFT) calculations and experimental electron energy-loss spectroscopy (EELS) was used to assess their bulk and surface plasmon responses. It was observed that Nax WO3 can sustain strong localised surface plasmon resonances (LSPR) with an energy that can be tuned by changing the Na content. They have a stronger plasmonic response when compared to Au and do not suffer from the atmospheric corrosion of Ag, giving them good potential for plasmonic applications
