Abstract

The development of a rapid response time, plastic optical fiber (POF) based oxygen sensor for the measurement of oxygen partial pressure (pO₂) is described. The POF oxygen sensor is based on the luminescence quenching of a luminophore by oxygen and consists of PMMA plastic optical fibre and a polymer matrix medium that contains immobilized Pt (II) complexes. The performance of the POF oxygen sensors was evaluated using luminescence intensity measurement. In order to accurately determine the response time of the POF oxygen sensors, a test chamber was used to provide rapid step changes in the partial pressure of oxygen. The details of the sensor chemistry, experimental system and the results are presented.
