A mini-goniometer for X-ray diffraction studies down to 4 K on four-circle diffractometers equipped with two-dimensional detectors
Autor: Pierre Fertey, Roger Argoud, Cyril Palin, Pierre Bordet, Emmanuel Wenger, Jacques Reymann, Rémi Bruyère, Christophe Bouchard, Claude Lecomte
Publikováno v: Journal of Applied Crystallography. 40:526-531
A `universal' low-temperature device for laboratory X-ray diffractometers equipped with two-dimensional detectors has been developed. Single-crystal data collections can be performed down to 4 K. Owing to its original design, the completeness of the

We present a new family of highly emissive white phosphors. These phosphors are based on original glassy yttrium aluminoborates (g-YAB) compositions, obtained at low temperatures without any melting, from non-toxic and low cost precursors through the
