“…8 Anthracene and its derivatives are model materials for triplet annihilation, often used for TTA-enhanced OLEDs, especially in the blue spectral range due to a relatively small conjugation length. 1 Nearly maximal values of EQE, peaking at 12%, 7−9 were achieved in anthracene-based OLEDs. Additionally, TTA-exhibiting anthracenes are also widely used in lowpower light upconversion, where low-energy photons are converted to high energy by TTA.…”

“…Besides singlet exciton fission, triplet exciton fusion can be observed in organic solids. This back transfer from the triplet to the singlet system is significant for increasing the efficiency of fluorescent organic light-emitting diodes 18,19 and is also responsible for the delayed fluorescence feature observed in time-resolved photoluminescence (TRPL) measurements as long-living luminescence tail. Triplet exciton fusion can only occur for 2ET1≥ES1.…”

“…It is well-known that anthracene-based luminophores are prone to undergo triplet-triplet annihilation upconversion [1][2][3][4]20,[25][26][27][28]37]. The nonlinear Luminance-Current density characteristics of the nondoped deep blue OLEDs at low current density (Fig.…”
