Single-Crystal Structure of HP-Sc2TeO6 Prepared by High-Pressure/High-Temperature Synthesis
Autor: Raimund Ziegler, Martina Tribus, Clivia Hejny, Gunter Heymann
Publikováno v: Crystals, Vol 11, Iss 12, p 1554 (2021)
The first high-pressure scandium tellurate HP-Sc2TeO6 was synthesized from an NP-Sc2TeO6 normal-pressure precursor at 12 GPa and 1173 K using a multianvil apparatus (1000 t press, Walker-type module). The compound crystallizes in the monoclinic space

Polymorphism and polymorph-dependent luminescence properties of the first lithium oxonitridolithosilicate Li3SiNO2:Eu2+
Autor: Kilian M. Rießbeck, Daniel S. Wimmer, Markus Seibald, Dominik Baumann, Klaus Wurst, Gunter Heymann, Hubert Huppertz
Publikováno v: Dalton Transactions. 52:4900-4910
A polymorph of the compound Li3SiNO2 has been synthesized via high temperature solid-state synthesis. The formation of the polymorphs, which show different luminescence properties when doped with Eu(ii), can be controlled very selectively.

Tb2Co(B2O5)2 and Tb2Cu(B2O5)2 – two new borates with gadolinite-type structures
Autor: Tobias A. Teichtmeister, Michael M. Hladik, Gunter Heymann, Hubert Huppertz
Publikováno v: Zeitschrift für Naturforschung B.
Using high-pressure/high-temperature synthesis methods, it was possible to increase the number of known borates with a crystal structure derived from gadolinite. Syntheses of Tb2Co(B2O5)2 (8 GPa, 1000 °C) and Tb2Cu(B2O5)2 (11 GPa, 650 °C) were carr

The crystal structure and luminescence properties of the first lithium oxonitridolithosilicate Li3SiNO2:Eu2+
Autor: Daniel S. Wimmer, Kilian M. Rießbeck, Markus Seibald, Dominik Baumann, Klaus Wurst, Gunter Heymann, Hubert Huppertz
Publikováno v: Dalton Transactions. 51:16465-16478
Obtained by a high temperature solid-state synthesis, the compound Li3SiNO2:Eu2+ was characterized via SCXRD, PXRD, and luminescence spectroscopy. This revealed a new structure type and interesting luminescence properties.
