Cover Feature: Towards White Light Emission Through Metal‐to‐Metal Charge Transfer (MMCT) Effect in Bi<sup>3+</sup> Activated Ca<sub>2</sub>YTi<sub>2‐m</sub>Zr<sub>m</sub>Ga<sub>3</sub>O<sub>12</sub> (0≤m≤2) Garnets (Chem. Eur. J. 17/2025)
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 (λem=395 nm) due to the 3P0,1→1S0 transition. After suitable modification, the compounds CYT:Bi and CYTZ:Bi emit white light.
