- Abstract
- In the quest for new functional materials, Mn2+-activated metal halide perovskites (MHPs) were found to possess remarkable optical properties. However, they show low photoluminescence quantum yield (PLQY) and weak thermal stability. This is due to weak dopant-host interactions and strong phonon-lattice coupling at high temperatures of MHPs. Developing Mn2+- activated MHPs with a high PLQY and good thermal stability has become a highly versatile research area to meet current needs. Herein, we synthesized Mn2+ ion-activated Rb-3(Cd1-xMnx)(2)Cl-7 layered metal halide perovskite (LMHP) and solved its crystal structure using direct methods. The Rb-3(Cd1-xMnx)(2)Cl-7 LMHP exhibits an orange emission with a high PLQY of 88%, the highest among Mn2+-activated MHPs. Moreover, Rh-3(Cd0.80Mn0.20)(2)Cl-7 exhibits a zero-thermal-quenching (TQ) behavior, which is considered the first for the MHP family. Therefore, our results could pave the way for a search for new LMHPs with zero-TQ behavior for high-power optoelectronic applications.
