Paper Abstract

Enhanced production of singlet oxygen, O2(a1Δg), was observed by reaction of O2/He discharge effluents on an iodine oxide film surface in a microwave discharge flow reactor at 320 K. We observed a two-fold increase in the O2(a) yields in excess of discharge-generated amounts for non-catalytic conditions. The iodine oxide surface appears to catalyze the heterogeneous reaction to form O2(a) with high collision efficiency. Injection of molecular iodine into the catalytically enriched active-oxygen flow resulted in excitation of the I(2P1/2) state approaching optical transparency at 1315 nm. Addition of NO2 resulted in positive small-signal gain in the 320 K subsonic flow. The observed catalytic effect could significantly benefit the development of electrically driven oxygen-iodine laser systems.
