Air stable and highly efficient Bi³⁺-doped Cs₂SnCl₆ for blue light-emitting diodes.

ABSTRACT: Cs₂SnCl₆ perovskite has recently attracted attention as a promising optoelectronic material owing to its better stability and reduced toxicity than its lead counterparts. However, its luminescence performance hardly satisfies the requirements. Hence, a series of Bi³⁺-doped Cs₂SnCl₆ (Cs₂SnCl₆:Bi³⁺) with enhanced luminescence were synthesized by a solution-phase route. The results show that the initial concentration of Sn²⁺ can adjust the nucleation density and the quality of the crystal nucleus growth, which will affect the Bi³⁺ doping amount, crystal morphology, and photophysical properties of Cs₂SnCl₆:Bi³⁺. Cs₂SnCl₆:Bi^3+<
