N2 - Li1.72Na0.28Ge4O9single crystal co-doped with Cr3+(0.1 mol%) and Mn2+(0.1 mol%) has been prepared by the Czochralski method. The electron paramagnetic resonance reveals presence of Cr3+and Cr3+-Li+/Na+pairs. Photoluminescence spectra show the sharp R1 and R2 emissions bands at 688-697 nm due to the 2Eg→4A2gtransition of Cr3+. They consist of three and two components, respectively. No emission from Mn2+is observed because of energy transfer to the 2Egstate of Cr3+. An effect of Mn2+in the co-doped crystals is discussed.
