What do you mean by an exciplex emission?

An exciplex is an excited-state complex formed between a molecule that donates electrons and one that accepts electrons. Exciplexes are generally of interest for their favorable light-emission properties. In particular, the excited state is readily able to undergo a process that enhances the efficiency of organic light-emitting diodes (OLEDs).The two molecules usually have to be within a few nanometers of each other for an exciplex to form.

What is excimer in chemistry?

An excimer is normally referred to as an unstable complex composed of a pair of an excited molecule and a ground-state molecule, which exists as long as one of the pair components is in the electronic excited state and which dissociates after photon emission of the pair has occurred.
