| Abstract: | The absorption and fluorescent spectra of mixed KCl-KBr crystals with lead admixtures were measured. A comparison with the absorption of analogical mixed solutions showed that the displacement of the absorption band of lead towards longer wave-lengths with increasing content of bromide is caused by the creation of mixed complexes. The latter are also responsible for the fluorescence of the crystals.
Die Verfasser danken herzlich Herrn Dr. A. Bohun für die wertvollen Diskussionen. Sie danken ferner Frau K. Dole alová für die Durchführung der Absorptionsmessungen der Kristalle und Frau M. Kubovská für die Züchtung der Kristalle. |
