Hybrid organic-inorganic Light Emitting Diodes

2013

Hybrid organic inorganic light emitting diodes are nowadays attracting great attention due to their intrinsic air stability and solution processability, which could result in low-cost, large area, light emitting devices. Despite the fact that high luminance values have been already demonstrated in recent publications, the efficiency of HyLEDs has been limited by its peculiar hole-dominated electronic mechanism. In particular, the electron injection is promoted by the hole accumulation at the metal oxide EIL/organic interface, but at the same time this mechanism leads to limits the device efficiency. It is known from the research in OLEDs that when the recombination zone is close to an inter…
