Organic light emitting diodes (OLEDs) employing organic thin‐film based emitters have
attracted tremendous attention due to their widespread applications in lighting and as …

1. INTRODUCTION Since Tang and Van Slyke invented the first efficient organic light-
emitting diode (OLED) based on small molecules in 1987, and Friend et al. in 1990, based …

Efficiency roll-off is a major issue for most types of light-emitting diodes (LEDs), and its
origins remain controversial. Here we present investigations of the efficiency roll-off in …

A general technique is demonstrated to quantify the contribution of monomolecular and
bimolecular quenching processes to the external quantum efficiency (EQE) roll-off in organic …

Triplet–triplet annihilation (TTA) is studied in a wide range of fluorescent host: guest emitter
systems used in organic light‐emitting devices (OLEDs). Strong TTA is observed in host …

We investigate the intrinsic degradation mechanisms of the prototypical phosphorescent
emissive material fa c-tris (2-phenylpyridine) iridium [Ir (ppy) 3] doped into the host 4, 4′-bis …

In this manuscript, we demonstrated a highly efficient DCJTB emission with delayed
fluorescent exciplex TCTA: 3P-T2T as the host. For the 1.0% DCJTB doped concentration, a …

Recent advances in organic light‐emitting diodes (OLEDs) based on thermally activated
delayed fluorescence (TADF)‐assisted fluorescence (TAF) attest to the great promise of this …

We show that the performance of organic light-emitting diodes (OLEDs) is markedly
improved by optimizing the thickness of a hole-injection layer (HIL) of molybdenum oxide …

In organic photovoltaics, high power conversion efficiencies (PCE) are mostly achieved on
device areas well below 0.1 cm2. Herein, organic solar cells based on a D18: Y6 absorber …
