The synthesis, structure determination, and intrinsic luminescent properties of a new tantalate, EuKNaTaO5, are reported. Single crystals of the title compound were grown out of a reactive KOH/NaOH eutectic melt. Luminescence in many materials is activated by doping a rare earth cation into the solid matrix; we report undoped, all-rare earth EuKNaTaO5, which exhibits bright orange room temperature photoluminescence.

Single crystals of two new barium rhodates were grown from a molten potassium carbonate flux. The new rhodates, Ba11Rh10O30 and Ba32Rh29O87, are structurally related to the 2H-hexagonal perovskite structure and are characterized by pseudo one-dimensional chains of alternating face-sharing trigonal prisms and octahedra. The structures of Ba11Rh10O30 and Ba32Rh29O87 were solved using the 4D superspace group approach in Jana2000. Ba11Rh10O30, with a repeat of nine RhO6 octahedra followed by one RhO6 …
Growth Of Sr6Rh5O15 Single Crystals From High Temperature Solutions: 1. Structure Determination Using The Traditional 3d And The 4d Superspace Group Methods. 2. Magnetic Measurements On Oriented Single Crystals, Katherine Stitzer, Ahmed Abed, Jacques Darriet, Hans Conrad Zur Loye

Single crystals of Sr6Rh5O15 were grown from a molten potassium carbonate flux. The structure was solved by both the traditional 3-D crystallographic approach and the 4-D superspace group approach using JANA2000. Both methods produced an equivalent structure determination, thereby confirming the 4-D superspace group approach as an effective structure solution method for 3-D commensurate composite structures. Sr6Rh5O15 corresponds to the n = 1, m = 1 member of the A3n+3mA‘nB3m+nO9m+6n family of 2H hexagonal …
