Organic semiconductors can be designed and constructed in π‐stacked structures instead of
the conventional π‐conjugated structures. Through‐space interaction (TSI) occurs in π …

Carbon neutrality, energy savings, and lighting costs and quality have always led to urgent
demand for lighting technology innovation. White light-emitting diodes (WLEDs) based on a …

Blue emitters with thermally activated delayed fluorescence (TADF) have the potential to
achieve 100% internal quantum efficiency, though the strategy to design stable blue TADF …

Since the development of the first white organic light-emitting device (OLED) in 1993, twenty
years have passed. The power efficiency and lifetime of this white OLED were reportedly …

Two novel thermally activated delayed fluorescence (TADF) emitters, 3-phenylquinolino [3,
2, 1-de] acridine-5, 9-dione (3-PhQAD) and 7-phenylquinolino [3, 2, 1-de] acridine-5, 9 …

Diffusion lengths of triplet and singlet excitons of the blue host are RT and RS, respectively …

Metal halide perovskites are essential materials with great potential for use in optoelectronic
devices, such as solar cells, flat-panel displays, solid-state lighting, and detectors, because …

Blue organic luminescent materials play a crucial role in full‐color display and white lighting
but efficient ones meeting commercial demands are very rare. Herein, the design and …

A new device architecture for highly efficient white organic light-emitting diodes is proposed,
using a molecule exhibiting blue thermally activated delayed fluorescence as a common …

Luminous efficacy (LE), which is given by the ratio of luminous flux to power, is commonly
used to measure the power consumption of a light source. Unfortunately, the LE of white …
