PHOSPHORESCENT OXYGEN SENSORS UTILIZING SULFUR-NITROGEN-PHOSPHORUS POLYMER MATRICES

Luminescent sensors based on composites comprising transition metal co mplexes immobilized in polymer matrices have attracted attention as ox ygen sensors for both biomedical and barometric applications. Typicall y, phosphorescent dyes are dispersed in a polymer matrix of high gas p ermeability are used, Here, S-N-P polymers are used as a novel matrix material allowing the sensitivity of the sensors to be controlled over a wide range.
