Beschreibung
Zusammenfassung:	A perovskite luminescent nanocrystal has a chemical formula represented by: Cs4BX6, wherein B includes one or more elements selected from the group consisting of Ge, Pb, Sn, Sb, Bi, Cu, and Mn and X includes one or more elements selected from the group consisting of Cl, Br, and I, wherein the Cs4BX6 perovskite luminescent nanocrystal has pure phase and a molar ratio of Cs to B (Cs/B) in the nanocrystal is greater than 1 and less than 4. This pure phase perovskite luminescent nanocrystal has well thermal stability and high quantum efficiency.
