Abstract: The broad emission band extending from 11000 to 6000 cm1 of both CrO43-- and MnO42--doped crystals is due to ligand-field transitions. The CrO43--doped systems have very low luminescence quantum efficiencies, even at 15 K, a severe restriction for their use as laser materials. MnO42--doped BaSO4 on the other hand has a relatively high quantum efficiency of 20% at room temperature which makes this a promising laser material.
