Exciton emission and emission by exciton-impurity complexes in CdxMnxSe crystals
Gubarev S. I., Shepel' B. N.
The state of an exciton complex on a neutral donor is energetically unstable due to the exchange interaction with a magnetic impurity. As a result, the line corresponding to recombination of exciton-impurity complexes disappears in the emission spectrum of Cd1 _ x Mnx Se in a magnetic field and the emission line of free excitons is excited.
