| 单词 | exciplex |
| 释义 | exciplex A combination of two different atoms that exists only in an excited state. When an exciplex emits a photon of electromagnetic radiation, it immediately dissociates into the atoms, rather than reverting to the ground state. A similar transient excited association of two atoms of the same kind is an excimer .

This is used in the exciplex laser , in which a population inversion is produced by an electrical discharge |
