- •
We have investigated the role of gold as catalyst and nucleation centers, for the crystallization and phase modification of tungsten oxide, in Au/WO3 matrix.
- •
The phase change from triclinic WO3 to monoclinic W18O49 is found to enhance with gold incorporation.
- •
The surface plasmon resonance is observed in gold/tungsten oxide system with the appearance of an absorption band near the wavelength 604 nm.
