F−center
Explanation:
When the electron takes the place of an anion in a crystal, then a non−stoichiometry arises. This extra electron is delocalised and when it absorbs light, it gets excited from ground state to higher energy state, and the crystal thus, appeared coloured. The site at which this extra electron is placed is called the F−center.
