  • Mechanisms of enhancement of light emission in nanostructures of II–VI compounds doped with manganese 
    Godlewski, M.; Yatsunenko, S.; Ivanov, V.Yu.; Drozdowicz-Tomsia, K.; Goldys, E.M.; Phillips, M.R.; Klar, P.J.; Heimbrodt, W. (Физика низких температур, 2007)
    Intra-shell transitions of transition metal and rare earth ions are parity forbidden processes. For Mn²⁺ ions this is also a spin forbidden process, i.e., light emission should be inefficient. Surprisingly, it was ...
  • Mechanisms of radiative and nonradiative recombination in ZnSe:Cr and ZnSe:Fe 
    Godlewski, M.; Surma, M.; Ivanov, V.Yu.; Surkova, T.P. (Физика низких температур, 2004)
    Possible applications of ZnSe:Cr in optoelectronics are discussed. It is shown that 2+ to 1+ photo-ionization of chromium results in efficient pumping of Cr²⁺ intrashell emission and in energy up-conversion from green ...
