Recently,  academician Huang Wei and Professor Chen Runfeng of the institute of  information materials and nanotechnology in our university have made  great progress in the field of organic afterglow. The achievement of  “Thermally activated triplet exciton release for highly efficient  tri-mode organic afterglow” has been published online in the  international top journal Nature Communications (Nature,  communications), which corresponding authors are professor Chen Runfeng  and academician Huang Wei to corresponding author, and Jin Jibiao, a  doctoral candidate is the first author of the paper.

　　The  team led by academician Huang Wei and professor Chen Runfeng  proposed that with the help of reasonable molecular design, long-lived  excitons can be transformed effectively and the luminous efficiency of  organic afterglow can be significantly enhanced. The  newly-produced afterglow materials have a lifetime of 0.23s and its  efficiency of up to 45%, which is the highest reported afterglow  efficiency so far. This study utilizes the newly developed afterglow  materials to expand the application in phosphorescent life imaging and  visual temperature detection. The developed thermal activation tri-mode  afterglow material can effectively enhance the afterglow efficiency and  represent an important progress in the field of highly efficient organic  afterglow.
