Vedclass · Answer

(D) An $F$-center (from the German word $Farbenzentrum$,meaning color center) is a type of crystallographic defect in which an anionic vacancy in a crystal lattice is occupied by one or more unpaired electrons.$1$. Electrons are trapped in the vacant sites of the crystal lattice to maintain electrical neutrality.$2$. These trapped electrons absorb light from the visible region,which imparts color to the crystal.$3$. The presence of these free electrons also contributes to the electrical conductivity of the crystal.Therefore,all the given statements are correct.
