This work demonstrates a versatile method known as CO2-laser pyrolysis which is used to synthesize high purity tungsten oxide thin films and nanostructures from gaseous-phase precursors. The results will show how laser pyrolysis can be used to control the phase and particle size of tungsten oxides by varying the laser power density and wavelength.
