      Recently, the team of Academician Tian He and Professor Ma Xiang of the School of Chemistry and Molecular Engineering of East China University of Science and Technology has made new progress in the research of organic room temperature phosphorescent materials
    .

      Pure organic room temperature phosphorescent materials with long afterglow have received widespread attention due to their application prospects in the fields of optoelectronics and biochemistry.
    How to construct long afterglow materials with different luminescent colors has always been a major difficulty in the field of pure organic room temperature phosphorescent materials

    .
    In addition to structural modification, the non-radiative energy transfer process is another feasible strategy to control the emission wavelength of phosphorescent materials

    .

      Based on this strategy, the researchers used different phosphorescent materials as energy donors, combined with light-responsive energy acceptor materials, to achieve reversible adjustment of the afterglow of different colors in the three states of solid state, solution state and gel state.
    Systematically characterize the emission spectrum, luminescence lifetime, excitation spectrum and other data of these materials in different states, and set up corresponding control experiments to prove the mechanism of radiant energy transfer

    .

      This strategy not only has a relatively simple working principle, but also has strong versatility and feasibility
