Abstract

The phosphorescence of PtOEP-C6/Poly (St-co-TFEMA) has been investigated to achieve an accurate oxygen content, which is always puzzled as its extreme temperature sensitivity. The relations of oxygen content and phosphorescence intensity ratio can be perfectly fitted by the Stern-Volmer equation at different temperatures, meanwhile the monotonic quenching constant K_SV is obtained, which enables us to develop a method of temperature correction to realize the intrinsic oxygen content. Then a clear fundamental picture of the temperature quenching mechanism of PtOEP is drawn by the time-resolved spectroscopy, the temperature sensitivity of phosphorescence arises from the enhanced quenching effect of oxygen by temperature. Our results provide an effective method to gain accurate oxygen content by simple optical measurement.
