抄録

A highly reliable optical sensor for oxygen-pressure measurements was developed. It was based on the phosphorescence quenching of platinum octaethylporphyrin incorporated in polymer films by oxygen. In this work, in order to overcome the shortcomings when the traditional spectrophotometer is used for oxygen sensing, the sensor behaviors were studied using a CCD-camera scanning technique. The Stern-Volmer plots of oxygen sensors showed improved linearity, compared with those of the traditional luminometer. The sensor was proved to have a good operational stability and <10% of the photobleaching was observed after storage for more than 1 year in the absence of light at room temperature.
