โœฆ Synopsis

A strongly lummescent platmum complex embedded m various sohd films was tested for eta characterlstlcs m optlcal oxygen sensmg m the gaseous state The effects of the munobdlzation procedures and the matnx materials on the degree of lummescence oxygen quenching of the complex were studled A model that combmed the quenchmg kmetics and the solublhty equation of oxygen m polymers IS proposed to correlate the decrease m lummescence mtenslly with the quencher concentration Thu model could explain the common feature of negatwe devlatlons from the Stem-Volmer equation of fluorophores bemg quenched m polymer films
