| dc.description | Zero-phonon lines are found at 732.7 nm in CaF<sub>2</sub> and 835.0 nm in SrF<sub>2</sub> when additively coloured crystals containing F<sub>3</sub> centres are exposed to ionizing radiations at low temperatures. The centres giving rise to these lines are not stable at room temperature. The maximum obtainable concentration of the centres is proportional to the number of F<sub>3</sub> centres present in the crystals. Measured uniaxial stress and electric field effects are similar to those found for F<sub>3</sub> centres. It is suggested that the new centres are negatively charged F<sub>3</sub> centres (i.e. F<sub>3</sub><sup>-</sup>). |
