What is the difference between excimer and exciplex?

Excimer or exciplex are the dimeric or heterodimeric short-lived species which can be generated in the excited state, but dissociate in the ground state. Generally, the homodimeric species in the excited state is termed as the excimer, whereas the heterodimeric species is known as the exciplex.
