This study explores the use of tin oxide (SnO2) and zinc oxide (ZnO) as electron injection layers (EILs) in OLEDs, comparing them to lithium fluoride (LiF). Devices with metal oxide EILs show improved electronic and optical properties, better charge injection, lower turn-on voltage, enhanced J-V-L characteristics, and higher external quantum efficiency (EQE), leading to longer device lifetimes.
