Abstract
As-anodized porous silicon (PS) was investigated in situ by photoluminescence (PL) during the adsorption of H 2O, O 2, C 2H 5OH and C 2(CN) 4 molecules. The PL intensity was increased during H 2O adsorption (to 130%) and decreased by adsorption of O 2 (to 30%), C 2H 5OH (to 22%) and C 2(CN) 4 (to 5%). A strong blue shift was observed during the C 2H 5OH adsorption. The reversibility of the adsorption-induced PL changes was compared for the different atmospheres. Reversibility by the simple cycle high vacuum pumping (HV)-adsorption-HV could be reached only for C 2H 5OH. The PL changes induced by H 2O and C 2(CN) 4 adsorption were good (H 2O) or partially (C 2(CN) 4) reversible in combination with heat treatment at 420 K in HV. The O 2-adsorption-induced PL changes are not reversible by simple or modified cycles.
