摘要：

A robust thin film dissolved oxygen sensor was fabricated by encapsulating platinum octaethylporphyrin (PtOEP) in an oxygen permeable elastic fluorinated co-polymer matrix. Phosphorescence, which was partially quenched by dissolved oxygen, was observed when the sensor was immersed in water. Aggregation of the dye was observed at elevated temperatures. Dye aggregate phosphorescence was not or only partially quenched by dissolved oxygen. The downward-turning Stem-Volmer plot was well fitted by a Langmuir adsorption isotherm. Good sensitivity, rapid response and photostability were observed for this detector. (C) 2003 Elsevier B.V. All rights reserved.
