Abstract

A photochemical new oxygen sensor using continuous wave Nd-YAG laser (CW laser) as an excitation light has been developed, which is based on the stationary state quenching of triplet-triplet (T-T) absorption of zinc 5,10,15,20-tetrakis-(pentafluorophenyl)-porphyrin (ZnTFPP) by oxygen. The intensity of ZnTFPP T-T absorption decreases with oxygen concentration, indicating the applicability for oxygen sensor.
