| Abstract | A photoluminescence (PL) response (S-band) of porous silicon to specific amounts of organic vapors of n-hexane, toluene and methanol in gas phase reveals the presence of two reversible processes: one relatively fast responsible for. PL quenching and one relatively slow which is responsible for a remarkable PL enhancement. The last PL quenching (with time constant of several seconds) can be utilized for sensing the studied organic vapors within a concentration range of about 1-500 ppm. |
