An optical oxygen sensor based on the photoluminescent quenching of palladium tetrakis(4-carboxyphenyl)porphyrin (PdTCPP) self-assembled membrane on an alumina plate has been developed. The luminescence intensity of PdTCPP membrane decreased with increase of oxygen concentration, indicating that this membrane is a highly sensitive device for oxygen concentration. The signal changes of this membrane are large enough to allow quantification of oxygen with good sensitivity (I-0/I-100 > 3). The response times of the sensor are 36 s on going from argon to oxygen and 148 s from oxygen to argon. This is a photostable sensing membrane that exhibits minimal decrease (ca 5%) in initial intensity after continuous irradiation for 24 h.
