General description

Tungsten(VI) oxide is an n-type oxygen deficient semiconducting metal oxide widely used to fabricate gas sensing devices.

It can also be used to prepare double perovskite materials for variousapplications.

Application

  • Coordination complexes of the tungsten (VI) oxide fluorides WOF4 and WO2F2 with neutral oxygen-and nitrogen-donor ligands: This study explores the coordination chemistry of tungsten(VI) oxide fluorides, which could be significant for researchers interested in the reactivity and applications of tungsten complexes (Levason et al., 2016).
  • Aerosol-assisted chemical vapor deposition of tungsten oxide films and nanorods from oxo tungsten (VI) fluoroalkoxide precursors: The study explores the deposition processes for creating tungsten oxide films and nanorods, relevant for applications in electronics and nanotechnology (Kim et al., 2015).
