Abstract

Li_1.72Na_0.28Ge₄O₉single 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 ²E_g→⁴A_2gtransition of Cr³⁺. They consist of three and two components, respectively. No emission from Mn²⁺is observed because of energy transfer to the ²E_gstate of Cr³⁺. An effect of Mn²⁺in the co-doped crystals is discussed.
