Optical absorption and photoluminescence spectra have been measured in LiF crystals colored for the first time with 5 MeV electrons. The measurements show that this kind of irradiation reduces (much more than γ-rays) the production of complex aggregate defects with respect to that of F+3and F2centers. Moreover, the laser active F+3centers can be preferentially created in place of F2centers by decreasing the irradiation temperature. © 1998 Elsevier Science B.V. All rights reserved.
