Formation of Cr2+-Fe2+ clusters in Zn0.7Mn0.3Se:Cr,Fe and Zn0.7Mg0.3Se:Cr, Fe crystals: Room-temperature spectroscopic properties and energy transfer
Original language description
The room-temperature spectroscopic properties of Cr2+ ions in Zn0.7Mn0.3Se and Zn0.7Mg0.3Se crystals co-doped with Cr2+ and Fe2+ ions were investigated and compared to Cr2+-only-doped ones. The "blue" shift of both absorption and fluorescence lines of Cr2+ ions in positions with nearby Fe2+ ions was demonstrated to be 350 cm -1 and 250 cm -1 for Zn0.7Mn0.3Se and Zn0.7Mg0.3Se crystals, respectively. This shift was shown to have a serious influence on the Cr2+-Fe2+ energy transfer process due to the worse energy resonance between Cr2+ and Fe2+ ions.
