Opto-electrical properties of single layer flexible electroluminescence device with ruthenium complex
| Summary: | In this work, a ruthenium hexafluorophosphate complex, [Ru(bpy)3](PF6)2 in poly(methylmethacrylate) (PMMA) was employed to build a single layer light electrochemical cell on indium tin oxide polyester flexible substrate. The electroluminescence spectrum features a relatively broad band peaked near 625 nm, with CIE (x, y) color coordinates of (0.61, 0.39). The driving voltage is only 3 V, and for the maximum electrical current of 10 mA the brightness reaches 1 cd/m2. Regarding the useful application of the device, its opto-electrical behavior under mechanical strain was studied considering the central curvature. In these situations, both electrical characterization in DC mode and luminance were analyzed. |
