Abstract
An organic light emitting device with a double-doped system, which in particular emits blue light, as well as a method for manufacturing such an organic light emitting device are disclosed. The organic light emitting device includes a substrate; a first electrode on the substrate; a second electrode opposite to the first electrode; and an organic light emitting layer between the first electrode and the second electrode. The organic light emitting layer includes a first dopant and a second dopant. With an organic light emitting layer including a first dopant and a second dopant, this disclosure achieves an organic light emitting device with a double-doped system, wherein different dopants emitting light of different colors are mixed into a same light emitting layer. This further improves a service life and light emitting efficiency of the light emitting device.
