Title: The effect of metal oxides on gasochromic properties of WO3 thin films formed by pulsed laser deposition (download abstract)

Supervisor: Prof. Seyed Mohammad Mahdavi

Gasochromic schematic
The optical properties of the gasochromic film changes when exposed to dilute H2 gas. The process is reversible by introducing O2 gas.

Schematic of the gas test experiment.
Gasochromic films under dilute H2 gas. The color difference is caused by varying the film concentration.
Gasochromic films under dilute H2 gas. The color difference is due to the presence of Ti, Mo, and Ni cations in the WO3 films.
