Tailoring photoluminescence stability in double perovskite red phosphors A₂BAlF₆:Mn⁴⁺(A = Rb, Cs; B = K, Rb)<i>via</i>neighboring-cation modulation

Abstract

We have effectively driven the photoluminescence stability in water tolerance and anti-thermal quenching behavior in double perovskite fluorides A₂BAlF₆:Mn⁴⁺(A = Rb, Cs; B = K, Rb)<italic>via</italic>modulating the neighboring cation on the A-site or B-site.
