Light-Emitting Devices Based on New Phenanthroline Derivates

Published Online: 2014-12-30 | DOI: https://doi.org/10.2478/aucts-2014-0013


An investigation of film forming properties, electrical characteristics, optical and electroluminescence properties of a recently synthesized pyrrolo[1,2-a][1,10]phenanthroline derivatives (RA) has been reported. The results indicate that these new materials can be used for manufacturing organic devices as lightemitting diodes. Various device structure and thickness have been considered in experiments. The poly(pphenylenevinylene)- PPV has been used as transporting layer while the RA as emitting layer. Good rectification behaviour with a switch-on voltage in range of 3 V and 7 V has been exhibited by these devices. Yellow-green light with of 96 cd⋅m-2 luminance has been found for the OLED based on the double layer structure 100 nm Indium Tin Oxide(ITO)/50 nm PPV/60 nm RA/100 nm Al
