Superluminescent halide perovskite light-emitting diodes with a sub-bandgap turn-on voltage
An emissive perovskite ternary composite thin film comprising a perovskite material, an ionic-conducting polymer and an ionic-insulating polymer is provided. Additionally, a single-layer LEDs is described using a composite thin film of organometal halide perovskite (Pero), an ionic-conducting polymer (ICP) and an ionic-insulating polymer (IIP). The LEDs with Pero-ICP-IIP composite thin films exhibit a low turn-on voltage of about 1.9V (defined at 1 cd m−2 luminance) and a luminance of about 600,000 cd m−2.
