Description
The vibronic structure on the optical absorption, emission, and excitation spectra of aggregates in Eu2+ -doped KCl and KBr crystals has been obtained. The crystals were annealed at 435 K. During the aggregation process, four groups of narrow bands were found in KCl: Eu2+ and two in KBr: Eu2+ ,which were considered as the signature of different Eu2+ -ion aggregated phases. The vibration frequency for each group is very similar. (Author)
