Abstract

Read online

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 decay rate constants, violating Kasha’s rule.
