Tuning The Plasmonic Response Of Tin Nanoparticles Synthesised By The Transferred Arc Plasma Technique

Titanium nitride exhibits plasmonic behaviour in the visible and NIR region. Combined with a refractory nature, it can be an attractive alternate plasmonic material useful in many applications. Despite the plethora of methods to produce TiN nanoparticles, it remains challenging to generate high quality TiN nanoparticles efficiently. Here we demonstrate the transferred arc plasma technique as a viable way to synthesise TiN nanoparticles. We show here that modulating the processing conditions can control the optical properties and tune the plasmonic response rendering the application of TiN nanoparticles viable across many applications.
