Thermally activated triplet exciton release for highly efficient tri-mode organic afterglow
Developing highly-efficient organic afterglow remains a formidable challenge. Here, we succeed in tuning the spin-forbidden phosphorescence of organic afterglow to spin-allowed fluorescence by thermally activated triplet exciton release and transformation, leading to a high efficiency up to 45%.
