Record-high efficiency in 1.54 µm electroluminescent diodes based on lead-free Cs3CrBr6: Er3+ semiconductor nanocrystals
The realization of efficient 1.54 µm electroluminescence from erbium ions is persistently hampered by their intrinsically small absorption cross-section and low excitation efficiency in conventional hosts. This study addresses this by synthesizing lead-free Cs3CrBr6 perovskite nanocrystals. This material is a direct-ba...
