Fine-tuning the thicknesses of organic layers to realize high-efficiency and long-lifetime blue organic light-emitting diodes

doi:10.1088/1674-1056/21/8/083303

Abstract By using p-bis(p-N, N-diphenyl-aminostyryl)benzene doped 2-tert-butyl-9, 10-bis-β-naphthyl)-anthracene as an emitting layer, we fabricate a high-efficiency and long-lifetime blue organic light emitting diode with a maximum external quantum efficiency of 6.19% and a stable lifetime at a high initial current density of 0.0375 A/cm². We demonstrate that the change in the thicknesses of organic layers affects the operating voltage and luminous efficiency more greatly than the lifetime. This lifetime independent of thickness is beneficial to achieving high-quality full-colour display devices and white lighting sources with multi-emitters.

Keywords: organic light-emitting diode blue emission lifetime organic layers thickness
