报告摘要 (Abstract)：

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.
