Zusammenfassung:Devices utilizing an entirely new class of earth abundant, inexpensive phosphorescent emitters based on metal‐halide nanoclusters are reported. Light‐emitting diodes with tunable performance are demonstrated by varying cation substitution to these nanoclusters. Theoretical calculations provide insight about the nature of the phosphorescent emitting states, which involves a strong pseudo‐Jahn–Teller distortion.
