Abstract

The emission behaviour of Bi³⁺ was explored in two different hosts, Ca₂YTi₂Ga₃O₁₂ (CYT:Bi) and Ca₂YZr₂Ga₃O₁₂: Bi³⁺ (CYTZ:Bi). A broad emission in the yellow–orange region in the former with a maximum at 552 nm was attributed to Bi³⁺–Ti⁴⁺ MMCT transitions. In the latter, the Bi³⁺ ions were found to emit in the violet region (λ_em=395 nm) due to the ³P_0,1→¹S₀ transition. After suitable modification, the compounds CYT:Bi and CYTZ:Bi emit white light. More information can be found in the Research Article by P. Thilagar, S. Natarajan and co-workers (DOI: 10.1002/chem.202404016).

期刊介绍： Chemistry—A European Journal is a truly international journal with top quality contributions (2018 ISI Impact Factor: 5.16). It publishes a wide range of outstanding Reviews, Minireviews, Concepts, Full Papers, and Communications from all areas of chemistry and related fields. Based in Europe Chemistry—A European Journal provides an excellent platform for increasing the visibility of European chemistry as well as for featuring the best research from authors from around the world. All manuscripts are peer-reviewed, and electronic processing ensures accurate reproduction of text and data, plus short publication times. The Concepts section provides nonspecialist readers with a useful conceptual guide to unfamiliar areas and experts with new angles on familiar problems. Chemistry—A European Journal is published on behalf of ChemPubSoc Europe, a group of 16 national chemical societies from within Europe, and supported by the Asian Chemical Editorial Societies. The ChemPubSoc Europe family comprises: Angewandte Chemie, Chemistry—A European Journal, European Journal of Organic Chemistry, European Journal of Inorganic Chemistry, ChemPhysChem, ChemBioChem, ChemMedChem, ChemCatChem, ChemSusChem, ChemPlusChem, ChemElectroChem, and ChemistryOpen.
