Popis:	— We achieved operationally stable white OLEDs with a single solution processed EML fabricated using a self-layered technique. An LT70 of 10 khr at an initial luminance of 1000 cd/m2 was obtained by suppressing the exciplex formation between the EML and ETL, preventing Li diffusion into the EMLs, and using red dopants with shallow LUMO levels and stable host materials.
