An oxygen sensitive polymeric material with enhanced photostability, comprising an oxygen sensitive indicator and photostabilizer incorporated into an oxygen permeable polymeric material is provided. The oxygen sensitive indicator can be, but is not limited to, [Ru(L1)(L2)(L3)]2+, wherein Ru represents the central ruthenium ion, L1, L2 and L3 represent the bidentate ligands diphenylphenanthroline, phenanthroline or bipyridine ligands or optionally substituted variations of same with representative counter ions selected from (PF6)-, Cl-, BF4-, Br- and (C 104)-, platinum or palladium based metallo- porphyrin. The photostabilizer is selected from CIBA TINUVIN 5236, TINUVIN 292, TINUVIN 123 and TINUVIN 272, TINUVIN 477W, DABCO and ascorbic acid. A sensor system for detecting oxygen and a method for detecting oxygen in a package is also provided. |
