Lead-free Cs₂Ag_1-xNa_xIn_1 - yBi_yCl₆ perovskite films with broad warm-yellow emission for lighting applications.

ABSTRACT: Lead-free halide double perovskite Cs₂AgInCl₆ has been extensively studied in recent years due to the lead toxicity and poor stability of common lead halide perovskites. In this study, sodium (Na⁺) and bismuth (Bi³⁺) doped into Cs₂AgInCl₆ double perovskite, then Cs₂Ag_1-xNa_xIn_1 - yBi_yCl₆ films with broadband warm-yellow emissions were achieved by the blade coating method. Herein, Na and Bi content were changed as variables at a series of parameter optimization experiments, respectively. In the Cs₂Ag_1-xNa_xIn_1 - yBi_yCl₆ systems, Na⁺ broke the parity-forbidden transi
