The properties of an optical sensor based on the oxygen-induced and temperature-induced luminescence quenching of tetrakis (pentafluorophenyl)porphyrinatoplatinum (PtTFPP) and 3,9-perylenedicarboxylic acid diisobutyl ester immobilized in a polystyrene film were investigated. The luminescence from PtTFPP in a polystyrene film was quenched by oxygen. On the other hand, the luminescence from 3,9-perylenedicarboxylic acid diisobutyl ester was not quenched by oxygen. Thus, the coincidence measurement for oxygen and temperature changes were attained using PtTFPP and 3,9-perylenedicarboxylic acid diisobutyl ester immobilized in polystyrene film.
