Opto-electrical properties of single layer flexible electroluminescence device with ruthenium complex

Abstract In this work, a ruthenium hexafluorophosphate complex, [Ru(bpy) 3 ](PF 6 ) 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/m 2 . 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.
