     the water vapor transmission rate (wvtr) is limited to 10−6 g/m2/day for flexible organic light-emitting diodes. however, it is difficult to measure permeability as low as 10−6 g/m2/day with current commercial testing methods. to address this need, a developed optochemical method which is extremely sensitive to oxygen or water shows promise. in this study, an eu complex is synthesized and characterized as a fluorescent probe for detecting traces of water molecules. the eu-complex film dispersed in poly(ethylene oxide) has strong red fluorescence that is easily quenched by a trace of water. based on the photoluminescence spectra, the detection limit of the film to water appears to be below 1.0 × 10−9 g/cc. this suggests that the eu-complex film can be used as a film sensor to measure wvtrs below 10−6 g/m2/day.
