Plasmonic Titanium Nitride Nanostructures via Nitridation of Nanopatterned Titanium Dioxide

Plasmonic titanium nitride nanostructures are obtained via nitridation of titanium dioxide. Results show that complex nano- and microscale designs of refractory plasmonic nitrides can be realized by utilizing the well-understood oxide material synthesis. Large-scale 3D nanoarchitectures will enable the use of refractory plasmonic materials in a variety of areas including spectrally and angularly selective metamaterials, plasmon-enhanced photocatalysis, and photothermal systems.
