Paper Abstract

Fe:ZnSe and other transition metals have broad upper and lower energy manifolds which give rise to broad absorption and fluorescence bands in the mid-IR spectral region. Energy transfer between Fe2+ ions via re-absorption of fluorescence (due to the spectral overlap of these bands) and phonon-assisted energy transfer (due to the lattice dynamics of ZnSe) becomes more probable with increasing Fe2+ concentration. Here we treat these processes as additional terms in the rate equations which govern the spontaneous decay of the Fe2+ ion. This treatment gives insight into anomalous behavior seen in the thermal lifetime of the Fe:ZnSe system. We also apply the model to other transition metal doped II-VI materials.
