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.

gas test schematic — 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.
