Crystal structures with symmetry are the art of nature – the electronic structure has its beauty, too. Read more about our results from a long-standing collaboration with colleagues from the Ivan Franko National University of Lviv, Ukraine:
Crystal and electronic structures of a new hexagonal silicide Sc38Co144Si97
A new publication from the group Phonon-Mediated Nonradiative Relaxation in Ln3+-Doped Luminescent Nanocrystals tackles the unsatisfactory photoluminescence efficiency of Ln3+-doped nanocrystals that severely restricts their practical application. The publication shows that phonon-mediated nonradiative relaxation in Ln3+-doped nanocrystals is substantially influenced by a variety of factors. Moreover, without explicit knowledge and consideration of these factors, property analysis will probably end up with misinterpretation. Thus the use of knowledge established for bulk materials to interpret the experimental findings collected at the nanoscale should be cautiously scrutinized. The authors conclude that systematic studies are needed for the informed development of Ln3+-doped luminescent nanomaterials that can meet the application needs for a sustainable society.
Frustration and 120° Magnetic Ordering in the Layered Triangular
Antiferromagnets AFe(PO3F)2 (A = K, (NH4)2Cl, NH4, Rb, and Cs)
The newest publication from the Mudring group is here! The paper presents a new family of layered iron oxofluorophosphates, AFe(PO3F)2, that were made by ionothermal methods using PF6 ionic liquids. In the context of frustrated triangular antiferromagnets, the close structural relationship between the layered compounds as well as polymorphism enables studying the magnetic properties as a function of cation identity and crystal symmetry.
Prof. Anja-Verena Mudring has just been named a fellow at the LE STUDIUM Loire Valley Institute for Advanced Studies!
Watch this space for exciting news about the collaborative research on ¨Lanthanide-based luminescent hybrid nanomaterials for theragnostic applications¨ with Svetlana Eliseeva & Stephane Petoud at Centre National de la Recherche Scientifique in Orléans.
From the group’s latest paper, relativistic effects show in chemical bonding: Bader analysis reveals a strong anionic character for the transition metals M = Pd, Pt in Ca3M4Bi8. Thus, the compounds have to be called a palladide and platinide, just like halides!

In the latest article from the Mudring group, they demonstrate that using ionic liquids as the reaction medium, structure templates, and mineralizer, all-in-one, allows for the design of transition metal fluorophosphate of varied dimensionality. Aside from engineering of magnetic exchange interaction, which is extremely exciting particularly from a fundamental viewpoint, their synthetic approach might lead to new battery cathode materials!

In a collaboration with colleagues from 5 countries, Siebeneichler et al. combined X-ray diffraction, magnetization and neutron diffraction to establish a universal phase diagram for ThCr2Si2-type solid solutions of REMn2X2. They were able to relate the emergence of magnetic incommensurability to structural features.
