Thermal plasma synthesis of tungsten bronze nanoparticles for near infra-red absorption applications

A novel synthesis concept based on inductively coupled thermal plasma technology is presented for the continuous high throughput production of tungsten bronze nanoparticles with high purity and tunable composition. Tungsten bronzes in nanoparticle form are of renewed technical interest for use in applications such as IR curing of coatings and heat shielding filters since they exhibit a high extinction coefficient in the near IR region but with little impact on transparency or visible color.
