CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishDiffuse reflectance spectroscopy in the UV-vis-NIR is employed to study the electronic transitions in MoO3-WO3 mixed oxide. The spectroscopic results were then related to the temp. profile of the surface barrier. The electronic absorptions appear to increase after reducing treatments and to decrease after oxidn. This variation of oxygen-related defects changes the doping level, which in turn, affects the dependence of surface barrier on temp. The latter is strictly connected to the sensing properties of the mixed oxide.

| Abstract: | Diffuse reflectance spectroscopy in the UV-vis-NIR is employed to study the electronic transitions in MoO3-WO3 mixed oxide. The spectroscopic results were then related to the temp. profile of the surface barrier. The electronic absorptions appear to increase after reducing treatments and to decrease after oxidn. This variation of oxygen-related defects changes the doping level, which in turn, affects the dependence of surface barrier on temp. The latter is strictly connected to the sensing properties of the mixed oxide. | |
