- Resumen
Recently developed organic light emitting diodes (OLEDs) show distinct advantages over their inorganic counterparts, due to their flexibility, high power efficiencies, transparency, and the possibility of large area deposition. However, high production costs due to expensive deposition techniques and the use of reactive materials still limit their market entry, highlighting the need for novel concepts.
Hybrid organic-inorganic light emitting diodes (HyLEDs) are inverted OLEDs that employ air stable metal oxides as the electron injection contacts. They are appealing for industrial applications, thanks to their intrinsic air stability and solution processability, which could result in low-cost, large area, light emitting devices.
The work presented in this thesis has evolved along the short history of this class of devices from its first discovery in 2006 and contains the present achievements in terms of efficiency and colour tunability. The presented data shed light on the electronic mechanism behind the functioning of HyLEDs and propose different strategies for their optimization, demonstrating how this novel class of devices can be a real competitor to standard OLEDs.
