The development of high-efficiency, stable and low-cost luminescent materials and devices is one of the most effective ways to achieve efficient use of energy, and is an important guarantee for our country's transition to a low-carbon economy. Metal-halide perovskites possess the advantages of both inorganic and organic materials, and have great potential for low-cost, large-area, flexible display and lighting applications. The core of the work of perovskite light-emitting devices is the carrier dynamics of the functional layer under the driving of electric/optical field. Therefore, the detection, understanding and manipulation the carrier dynamics in perovskite by tailoring the materials¡¯ dimensionality and size are the key scientific issues in this field. In this report, we will introduce our discoveries on the excellent luminescent properties of metal-halide perovskites, the detection and regulation of carrier dynamics, research works on performance optimization of light-emitting devices and development of new luminescent applications.
