Abstract
Cationic terbium complexes bearing an N-methylphenanthridinium chromophore have been incorporated in sol–gel thin films and their response characteristics analysed with respect to variations in dissolved oxygen concentration. Analysis of the emission lifetime decay curves (547 nm) has allowed a linear calibration model to be defined over an oxygen concentration range from zero to 0.5 mM (H2O, 295 K).Keywords
