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.
