Description

New germanates with the NdAlGe2O7-type structure are synthesized. The Czochralski method is used to grow LaGaGe2O7:Nd3+ single crystals and the full concentration series of Gd1-xNdxGaGe2O7 crystals. The GdGaGe2O7 crystal structure is refined. The absorption-luminescence properties of the grown crystals have been studied. The main intensity parameters of luminescence are determined. The stimulated emission of the crystals including that of self-activated NdGaGe2O7, are excited for two lasing 4F3/2 →4I11/2 and 4F3/2→4I13/2 channels, using the conventional lamppumping technique at 300 K. All the observed induced transitions are identified. (author)
