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.

Thermally activated delayed fluorescence (TADF) is a mechanism by which triplet state electrons can be harvested to generate fluorescence. TADF materials (also known as TADF emitters) efficiently convert triplet excitons back to the emissive singlet state through reverse inter-system crossing (RISC). This process requires a small amount of ...

Nov 11, 2021 · TADF scintillators exhibit the desirable and rare combination of high conversion efficiency, large Stokes shift, fast light decay and full spectral availability.

Jan 15, 2024 · TADF is another emission technique that is gaining popularity. In this technique, thermal energy is used to convert an electron in a triplet excited state to a singlet excited state, where it then emits in a fluorescence event.

Mar 26, 2025 · The present study provides insight into how dual TADF-TTA delayed fluorescence can be realized in thin films of molecular semiconductors via rational molecular design.

Jul 13, 2021 · Thermally Activated Delayed Fluorescence (TADF) is a mechanism for enhancing the efficiency of Organic Light Emitting Diodes (OLEDs) by harvesting triplet excitons. TADF has therefore attracted widespread interest in the OLED community and research into TADF and OLEDS is a popular application of our FS5 and FL1000 photoluminescence spectrometers.

Aug 9, 2022 · We present a detailed and comprehensive picture of the photophysics of thermally activated delayed fluorescence (TADF). The approach relies on a few-state model, parametrized ab initio on a prototy...

Apr 8, 2020 · Using kinetic equations analogous to those presented in section 2.2, Palmeira et al. 108 established the different requirements for molecules exhibiting two-step TADF (ISC followed by rISC) and one-step TADF (just rISC) applicable to photo and electrical excitations, respectively.

Jun 17, 2021 · Communications Chemistry - The process of thermally activated delayed fluorescence (TADF) converts non-radiative triplet states into emissive singlet states. Herein we outline the fundamentals...

In recent years, thermally activated delayed fluorescence (TADF) has attracted much attention as a novel electronic transition process, since it enables harvesting electrically generated triplet energy as EL without the utilization of rare metals such as iridium and platinum.
