Information × Registration Number 0211U007820, 0111U005375 , R & D reports Title Development of methods of improving efficiency of light emitting elements based on organic materials for microelectronics devices popup.stage_title Head Volynyuk Dmytro Yurijovych, Registration Date 12-10-2011 Organization Lviv Polytechnic National University popup.description2 Optimized technology of forming thin films of copper iodide and derivative-based pirazolinu (HPhP) method thermovacuum application. Multilayered heterostructures of CuI film thickness close to 12 nm are characterized light emitting optimal performance, by the balance between the injected electrons from an aluminum cathode and holes from the ITO anode and the separation zone recombination of charge carriers from the ITO electrode interface. When using film HPhP as hole transport layer for OLED (ITO/HPhP/AlQ3/Al), the minimum voltage inclusion of this device is 6.7 V, maximum current efficiency of 9.75 cd / A and brightness of 6568 cd/m2 (at 14.38 V). The presence of phenol in the screened hole transport layer leads to slower degradation processes in OLED.
