Résumé :

The Carbon dioxide (CO2) is a greenhouse gas, hence, its increase contributes to global warming. Titanium dioxide (TiO2) emerging as important material for use in gas sensors. . In this paper, TiO2 thin films was prepared by RF-DC magnetron sputtering on to glass substrates, under argon and oxygen atmosphere. In the aim to prepare TiO2 film which were applied in the gas detection sensor of carbon dioxide, various parameters such as working pressure (50mTorr, 100mTorr, and 150mTorr), flow of Ar and O2 and also substrate temperature have been considered.
