Crystal structure of strontium praseodym aluminate, SrPrAlO4

Crystal structure of strontium dinickel iron orthophosphate

The title compound, SrNi2Fe(PO4)3, synthesized by solid-state reaction, crystallizes in an ordered variant of the α-CrPO4 structure. In the asymmetric unit, two O atoms are in general positions, whereas all others atoms are in special positions of the space group Imma: the Sr cation and one P atom occupy the Wyckoff position 4e (mm2), Fe is on 4b (2/m), Ni and the other P atom are on 8g (2), on...

Understanding surface structure and chemistry of single crystal lanthanum aluminate

The surface crystallography and chemistry of a LaAlO3 single crystal, a material mainly used as a substrate to deposit technologically important thin films (e.g. for superconducting and magnetic devices), was analysed using surface X-ray diffraction and low energy ion scattering spectroscopy. The surface was determined to be terminated by Al-O species, and was significantly different from the i...

Nanosized strontium aluminate phosphors prepared via a reverse microemulsion route

Nanosized strontium aluminate phosphors co-activated by Eu2+ and Dy3+ were prepared via a novel reverse microemulsion process. This new ynthesis technique lowered the synthesis temperature of SrAl2O4: Eu2+, Dy3+ phosphors to as low as 900 ◦C, and also reduced the particle size o the nanometer scale (around 40 nm). In the microemulsion process, the constituent cations were trapped by numerous na...

Improved performance of strontium aluminate luminous coating on the ceramic surface

Crystal structure of strontium dicobalt iron(III) tris­(orthophosphate): SrCo2Fe(PO4)3

The title compound, SrCo2Fe(PO4)3, has been synthesized by a solid-state reaction. It crystallizes with the α-CrPO4 type structure. In this structure, all atoms are on special positions of the Imma space group, except for two O atoms which are located on general positions. The three-dimensional network in the crystal structure is made up of two types of layers stacked normal to (100). The first...
