Titelbild: Photolumineszenz Von Mn2+ in Dem Borosulfat Zn[B2(SO4)4] : Mn2+ – Eine Möglichkeit Zum Nachweis Schwach Koordinierender Liganden (angew. Chem. 45/2023)

Mn2+ is a so-far still rather underestimated visible emitter that is more abundant than the currently dominantly used emitter Eu2+. This could be a possible alternative for future LED phosphors. The cover picture shows octahedrally coordinated Mn2+ ions embedded in the borosulfate Zn[B2(SO4)4]. Borosulfates are weakly coordinating ligands, which is directly reflected in the photoluminescence properties of the Mn2+ ions: They show orange narrow emission, which is indicative for a weak octahedral ligand field, as explained by Jörn Bruns, Markus Suta et al. in their Research Article (e202309212).
