पर्याय

• Schottkey defect

• Frenkel defect

• Stoichiometric defect 

• F-centres

Answer 1

When electrons are trapped into the crystal in anion vacancy, the defect is known as F-centres.

Explanation:

Due to a hole being left in the lattice where a negative ion should have been, which is now filled by an electron. F-centers are the electrons that are subsequently trapped in anion vacancies.
