Abstract: Spectroscopic properties of Cr$^{2+}$ and Fe$^{2+}$ ions in Zn$_{1-x}$Mn$_x$Se solid solution with $x$ = 0.05 content $x$ = 0.3 and $x$ = 0.3 at low (77 K) temperature are investigated and their difference for crystals doped only by chromium ions and co-doped by chromium and iron ions is demonstrated. This difference is attributed to formation of Cr$^{2+}$–Fe$^{2+}$ clusters in co-doped crystals.

Keywords: Zn$_{1-x}$Mn$_x$Se based solid solutions, Cr$^{2+}$–Fe$^{2+}$ ions co-doping, spectroscopy, clustering.
