Abstract

We have observed a new broad-band luminescence, with a peak at 626.5 nm, additively-coloured BaF₂, but only when exciting on the long wavelength side of the F-centre absorption band. Such emission could originate in one of the many complex centres which are created in such materials by additive colouration. However, the special conditions required for its observation as well as the mirror-image symmetry of the emission band with respect to the F-centre absorption band suggest that the emission may originate in isolated F-centres. To our knowledge, such emission has not been reported for any of the alkaline-earth fluorides.
