Phosphorescent oxygen sensors utilizing sulfur–nitrogen–phosphorus polymer matrices
Source abstract
Abstract
Luminescent sensors based on composites comprising transition metal complexes immobilized in polymer matrices have attracted attention as oxygen sensors for both biomedical and barometric applications. Typically, phosphorescent dyes are dispersed in a polymer matrix of high gas permeability 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.

27. Usually the Stern–Volmer equation employed in the literature is expressed in a form which reflects its derivation from a consideration of the chemical kinetics of quenching in fluid media i. e. Io/I = 1 + ksv[Q] where ksv= kqτ0and kqis the bimolecular rate constant of quenching 0is the lifetime of the excited state of the dye in the absence of gaseous quencher and [Q] is the concentration of quencher (see Ref. 12a). In this paper the use of the intensity at I atm (i. e. I1(x)) as the point of reference is for convenience only and for each case the reader can calculate ksvfrom the relation ksv= (B/A).
