Abstract

The measurement of oxygen concentration is essential in many different research fields, including medicine, biology, industry, environmental sciences, automotive and aerodynamics [1]. Dissolved oxygen concentration is another important parameter to be determined for assessing water quality, including water purification, fish and algae farming and industry processing [2].

Abstract

This work describes the develepment of an optical oxygen sensor based on the phosphorescence quenching of organometallic complexes. The sensor is based on Pt(II) Octaethylporphyrin dispersed in a polymeric matrix. A green LED and a photodetector are used to excite and to measure the luminescence signal. The sensor allows for the measure of both gaseous and dissolved oxygen. The sensor can be operated around the atmospheric oxygen pressure; this makes it suitable for the measurement of oxygen content in exhaled breath.
