Efficient Low-Temperature Solution-Processed Lead-Free Perovskite Infrared Light-Emitting Diodes
Lead‐free perovskite infrared light‐emitting diodes are achieved by using a halide perovskite CsSnI3 as an emissive layer. The film shows compact micrometer‐sized grains with only a few pinholes and cracks at the grain boundaries. The device exhibits maximum radiance of 40 W sr−1 m−2 at a current de...

| description | Lead‐free perovskite infrared light‐emitting diodes are achieved by using a halide perovskite CsSnI3 as an emissive layer. The film shows compact micrometer‐sized grains with only a few pinholes and cracks at the grain boundaries. The device exhibits maximum radiance of 40 W sr−1 m−2 at a current density of 364.3 mA cm−2 and maximum external quantum efficiency of 3.8% at 4.5 V. |
