Thermally activated delayed fluorescence (TADF) is a process through which surrounding thermal energy changes population of excited states of molecular compounds and thus, alters light emission.

Oct 13, 2022 · Organic light emitters based on multiresonance-induced thermally activated delayed fluorescent materials have great potential for realizing efficient, narrowband organic light-emitting diodes...

Jul 7, 2024 · TADF OLED emitters, or Thermally Activated Delayed Fluorescence, is a relatively new class of OLED emitter materials that promise efficient and long-lifetime performance without any heavy metals. TADF research started in earnest in 2012, and the first TADF emitters reached commercial status at the end of 2019.

Thermally activated delayed fluorescence (TADF) has emerged as a promising mechanism for achieving efficient light emission in OLEDs. TADF materials, which engage the mechanism of reverse intersystem crossing (RISC) to convert non-radiative triplet excitons into radiative singlet excitons, offer a pathway to overcome these challenges.

Apr 10, 2018 · Thermally activated delayed fluorescence (TADF) emitters, which produce light by harvesting both singlet and triplet excitons without noble metals, are emerging as next-generation organic...

Nov 11, 2024 · The rates of reverse intersystem crossing (k RISC TADF) and the triplet-singlet Förster resonance energy transfer (k T-SFRET Ph-G) are the decisive factors in the internal quantum efficiency (IQE) of the TSF and the PSF systems, respectively.

Mar 21, 2025 · However, the OLEDs based on MR-TADF emitters usually show large EL efficiency roll-offs because of the intrinsic slow reverse intersystem crossing (RISC), whose rate constant is around 1% of those of traditional D-A–type TADF emitters (), greatly limiting their practical applications.To address this issue, a sensitization strategy, namely hyperfluorescence (HF), is proposed for the design of ...

Apr 8, 2020 · In this article recent progress in the development of molecules exhibiting Thermally Activated Delayed Fluorescence (TADF) is discussed with a particular focus upon their application as emitters in highly efficient organic light emitting diodes (OLEDs).

Mar 26, 2025 · Single-molecule emitters with dual thermally activated delayed fluorescence (TADF) characteristics are very promising for application in organic light-emitting diodes (OLEDs). Rarely reported, organic dual-TADF materials, especially mechanochromic materials, are in demand. We present two donor–acceptor emitters, Mes*BA-Ac and FXylBA-Ac, which exhibit dual-TADF in the solid state due to the ...
