Abstract:
1. An organic light-emitting diode comprising a substrate, an organic light-emitting layer arranged between a first electrode and a transparent and semi-reflecting second electrode with a multilayer structure subdivided into: a first silver-based metallic layer in contact with the organic light-emitting layer, a second aluminum-based metallic layer, and and a third dielectric layer, the second metallic layer being inserted between the first metallic layer and the third dielectric layer of the transparent second electrode, the organic light-emitting layer comprising a doped sub-layer in contact with the first metallic layer of the transparent second electrode, and a thickness of said third dielectric layer being adjusted to limit absorption by said first and second metallic layers of light emitted by the organic light-emitting diode, the second metallic layer having a thickness between 3 and 10 nm, and a thickness of the first metallic layer being larger than the thickness of the second metallic layer.
