The crystal structure of terbium(III) scandate(III), with ideal formula TbScO3, has been reported previously on the basis of powder diffraction data [Liferovich & Mitchell (2004). J. Solid State Chem. 177, 2188–2197]. The current data were obtained

We experimentally evaluated segregation of Cr, Ce and Al in bulk β-Ga2O3 single crystals grown by the Czochralski method, as well as the impact of these dopants on optical properties. The segregation of Cr and Ce and their incorporation into the β-

Aluminium grain boundary diffusivities were measured in pure and Y-doped polycrystalline alpha-Al2O3 using the artificial aluminium isotope Al-26 as a tracer. An advanced preparation technique for the Al-26 tracer source enabled secondary ion mass sp

A cylindrical cerium doped CaSc2O4 bulk single crystal with a diameter of 20 mm and a total length of 70 mm was grown from the melt by the Czochralski method. Due to competitive growth and grain selection, the crystal shows high crystalline quality,

The pseudobinary system LaLuO3–LaScO3 was explored in hopes of discovering new perovskite-type substrates with pseudocubic lattice parameters above 4 A. A complete solid solution of the type (LaLuO3)1−x(LaScO3)x forms between the end members LaLu

A modified approach of the fluorolytic sol–gel synthesis was used to synthesize pure, amorphous aluminum hydroxide fluorides with very low and easily adjustable fluorination degrees, as well as controllable surface areas. The careful investigation

A variety of SrTiO3 (STO) fibers have been grown by the laser-heated pedestal growth method to determine the influence of the oxygen partial pressure in the growth atmosphere and the composition of the feed material on the coloration of SrTiO3. Cryst

SrTiO3 crystals grown by the top-seeded solution growth method in air show different shades of light brown coloration, depending on the growth conditions. In the optical transmission spectrum this is manifested as a broad absorption, tailing off from
