Abstract
： Due to their unique structures and excellent optoelectronic properties ， two - dimensional （ 2D ） materials and their heterostructures are promising materials for the next generation optoelectronic technology. The dynamic properties of photocarriers have an important influence on the optoelectronic properties of these materials. This re⁃ view discusses the research progress in recent years on the photocarrier dynamics in these materials. In the time do⁃ main ， transient absorption measurements of carrier thermalization ， energy relaxation ， exciton formation ， exciton - ex⁃ citon annihilation ， and exciton recombination in 2D materials are discussed. In the spatial domain ， high - spatial - reso⁃ lution transient absorption microscopy studies of photocarrier in - plane transport properties are introduced. Further⁃ more ， interlayer charge and energy transfer in 2D heterostructures are discussed.
期刊介绍：
Chinese Journal of Luminescence (CJL), supervised by Chinese Academy of Sciences (CAS), Sponsored by Committee on luminescence of Chinese Physical Society and Changchun Institute of Optics, Fine mechanics and Physics（CIOMP）of Chinese Academy of Sciences, is an authoritatively scientific and technical periodical of China in the field of luminescence, which is read widely in providing original papers and reviews that describe recent developments on basic theory and experimental studies of excited state processes and green lighting projects. The journal was established at 1980, and named after LUMINESCENCE AND DISPLAY, then renamed as CJL in 1986.
