However, it is difficult to measure permeability as low as 10−6g/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 1.0×10−9g/cc. This suggests that the Eu-complex film can be used as a film sensor to measure WVTRs below 10−6g/m2/day.
