EA

Electron Affinity

The energy released when an electron is added to an atom. If the electron affinity is negative, then energy is required to attach an electron to the atom.

EBL

Eectron Block Layer

This layer confines electrons to the emitting layer. 

EIL

Electron Injection Layer

An electron injection layer facilitates electron injection from the cathode to the organic layer.

EL

Electro-Luminescence

Electro-Luminescence is the process of light emission under electrical excitation. 

EML

Emitting Layer

In the emitting layer electrons and holes recombine under light emission. 

ETL

Electron Transport Layer

This layer transports the electrons to the emitting layer.
