Complex centers in γ-irradiated LiF:Cu2+ crystals
- 1. Rome Univ. (Italy). Ist. di Fisica
Description
Optical spectra of γ-irradiated LiF:Cu2+ crystals are measured as a function of impurity concentration and coloration intensity. New defects are revealed by means of their luminescences and tentatively identified as aggregate color centers associated with the dopant ions. F2 centers coupled to Cu2+ ions show absorption at 375 nm and emission at 500 nm, while F3+ centers coupled to Cu2+ ions exhibit absorption at 470 nm and luminescence at 570 nm. (orig.)
