Sapphire Luminescence - F Centers

From Emerging Material Technologies (EMT, Inc.)
 

 

On the basis of an extensive study of the optical behavior of neutron-bombarded crystalline sapphire we proposed that oxygen vacancies with one electron (F centers) and two electrons (F centers) are responsible for the 4.8 and 6.1 eV absorption bands, respectively. This defect model has been supported by the recent experimental studies of Evans, who, in addition, found evidence for attributing absorption at 5.4 and 6.0cV to the F center as well.
