    Abstract

    This paper presents the development of a novel
    luminescence-based trace oxygen sensor that will eventually lead
    to the production of a commercial sensor for use in gaseous
    sensing applications. The proprietary sensing formulation
    provides the means of a robust and stable sensor using a
    metalloporphyrin complex as the luminescent indicator that is
    efficiently quenched by oxygen. The spectroscopic properties of
    the oxygen sensitive layer have been carried out and appropriate
    optical components and electronics sourced and built into a low
    cost, compact, miniaturized device. This novel oxygen sensor
    operates in the 0–10,000 parts per million (ppm) range and offers
    an alternative to traditional trace oxygen sensors, such as
    galvanic electrochemical, zirconia and other luminescence-based
    ppm sensors.
