title: High-performance quenchometric oxygen sensors based on fluorinated xerogels doped with [Ru(dpp)3]2+.
abstract: By using hybrid xerogels that are composed of alkyl and perfluoroalkyl ORMOSILs (organically modified silicates) doped with the luminophore tris(4,7'-diphenyl-1,10'-phenanthroline) ruthenium(II), we have produced highly sensitive O2 sensors (i.e., I(N2)/I(O2) = 35 +/- 4) with linear calibration curves that exhibit less than 2% drift over 6 months.
