摘要
Light-emitting diodes(LEDs)have wide applications in the areaof lighting,medical devices,display screens,etc.Owing to theexcellent optoelectronic properties and the facile solution proces-sing methods,organometal halide perovskites are extensively stu-died and proved to be promising light.emitting materials to fabri-cate LED devices[1-2].Generally,nonradiative recombination andlight trapping are two main factors to impede the efficiency en-hancement of LEDs,which are more serious in perovskite mate-rials for the high refractive index.
