Abstract:
We demonstrate coexistence of slow and fast components of photolumi-
nescence decay of the Mn2+ intra-shell emission in nanoparticles of CdMnS.
We explain the observed decrease in PL lifetime of the Mn2+ intra-shell tran-
sition by high efficiency of spin dependent magnetic interactions between
localized spins of Mn2+ ions and free carriers. This mechanism is enhanced
in nanostructures, but it is also present in bulk samples.
