Organic-inorganic halide perovskites have attracted considerable attention owing to their outstanding solar cell ***,these halide perovskites exhibit good light emitting in visible and near-infrared range with high fluorescence quantum yield,resulting in ***,it remains challenging for lighting and display due to the low luminance and poor long-term ***,high performance green light-emitting diodes are fabricated from bromine based perovskite(CH3NH3Pb Br3) by systematically adjusting the preparation conditions and optimizing the emitting layer thickness.A high luminance up to 1500 cd m-2(one of the highest values for perovskites-based light-emitting diodes) was achieved with 80 nm perovskites-emitting layer,due to the well-crystallized,full-coverage property of the *** result further confirms the great prospect of organic-inorganic perovskites in optoelectronics.
