Enhancing Stability of Microwave‐Synthesized Cs2SnxTi1‐xBr6 Perovskite by Cation Mixing

open access: yesChemSusChem, Volume 18, Issue 9, May 5, 2025.
This research introduces a microwave radiation synthesis technique for synthesizing Cs2SnxTi1‐xBr6 lead‐free double perovskite powders. By incorporating Sn4+ cations, the stability of the material is improved, particularly at elevated temperatures and outside conditions.
