Abstract

We report the microphoto-luminescence band redshifts with individual and multi-Mn(II) ion emissions within CdS microwires. The localized exciton magnetic polarons (LEMPs) corresponding to the d - d optical transitions of Mn(II) account for this shift. This LEMP emission from the double-, three- and four-Mn(II) ions with ferromagnetic coupling after photoexcitation can happen in diluted magnetic semiconductors, except for the individual Mn(II) doping. In addition, a simple spin-exchange polaronic model is established to account for these emission peaks well. Through this model, we can verify the local geometry of the Mn(II) ions in CdS microwires.
