Paper Abstract

Sol-gel materials were developed for potential fiber optic applications as films for detecting dissolved H2S and H2S vapor. Modification of the optical properties of gels were recognized by simply changing a processing parameter such as the type of catalyst of the introduction of a second precursor. Other properties such as chemical durability and photostability were also evaluated. Finally, the fluorescence quenching of thionin doped gels by dissolved H2S revealed a sensitivity and reversibility in the parts-per-billion regime. After performing these preliminary steps to assess the gel's integrity, the thionin doped gel is now read for H2S monitoring.
