Highly Tunable Emission by Halide Engineering in Lead-Free Perovskite-Derivative Nanocrystals: The Cs(2)SnX(6) (X = Cl, Br, Br/I, I) System

Nanocrystals of Cs(2)SnX(6) (X = Cl, Br, Br(0.5)I(0.5), and I) have been prepared by a simple, optimized, hot-injection method, reporting for the first time the synthesis of Cs(2)SnCl(6), Cs(2)SnBr(6), and mixed Cs(2)Sn(I(0.5)Br(0.5))(6) nanocrystalline samples. They all show a cubic crystal structu...

description Nanocrystals of Cs(2)SnX(6) (X = Cl, Br, Br(0.5)I(0.5), and I) have been prepared by a simple, optimized, hot-injection method, reporting for the first time the synthesis of Cs(2)SnCl(6), Cs(2)SnBr(6), and mixed Cs(2)Sn(I(0.5)Br(0.5))(6) nanocrystalline samples. They all show a cubic crystal structure with a linear scaling of lattice parameter by changing the halide size. The prepared nanocrystals have spherical shape with average size from 3 to 6 nm depending on the nature of the halide and span an emission range from 444 nm (Cs(2)SnCl(6)) to 790 nm (Cs(2)SnI(6)) with a further modulation provided by mixed Br/I systems.
