Promising next generation of Flexible electronics which are flexible e-book, thin film solar cell, flexible lighting, and flexible OLED provide the availability of robust, light weight, portable and rollable function. However, one of the major obstacles of the technology is the extraordinary sensitivity of organic based active materials to water trace and oxygen molecules. The requirement of WVTR (Water Vapor Transmission Rate) is 10-6g/m2/day for flexible OLED. However, it is difficult to measure the permeability of 10-6g/m2/day by current technologies like MORCON, calcium to jump over the hurdle; opto-chemical method is promising using luminescent nana-materials, which are sensitive to oxygen or water. It can be used for not only estimating the permeability of a trace of target molecules, but also measuring defect of barrier film which affects its WVTR. In this study, Eu-complex is synthesized and characterized as a fluorescent material for detecting a trace of water molecule. Eu-complex is incorporated in poly (ethylene oxide). Eu-complex in polymer matrix is not tricky to manage. It has strong red-fluorescence, but is easily quenched by a trace of water. The optical property and water sensitivity of the film which is incorporated with Eu-complex has been investigated and characterized using SEM, Ellipsometry, Uv-vis, and PL spectrometer.
