A direct observation of up-converted room-temperature phosphorescence in an anti-Kasha dopant-matrix system

Nature Communications, 2023
The emission maximum of phosphorescence is normally larger than that of fluorescence. Here, authors report up-converted room-temperature phosphorescence materials that emit from higher-lying triplet states with 3n-π* characters and large phosphorescence ...
