Notes:
New insulating Bi14(Sr0.33Ca0.67)5O26 layered single crystals have been grown by a flux method and their crystallographic properties have been characterized. The crystals exhibited a smooth cleaved surface perpendicular to [001] orientation. The x-ray precession camera analysis indicated the crystals have rhombohedral symmetry, belonging to a Laue group of 3¯m. Furthermore, some kinds of rare-earth elements have been successfully substituted for lattice sites of the crystal. The variation of the c-axis length reflected ionic radii of the rare-earth elements substituted. Radiant luminescence has been observed in visible and infrared regions in the Er-doped crystals, which was assigned to electron transition between spin-orbit levels of trivalent Er ions in the crystal.
