Abstracts

EN

The Eu-connected recombination processes in ZnS and CaS are analyzed on the basis of optical studies. A new Eu-related emission in ZnS is attributed to the recombination of an exciton bound at the Eu^{2+} center, while in CaS the emission is dominated by the direct Eu^{2+} intra-ion transition.
