Two-photon absorption (2PA) is a third-order non-linear optical process in which a molecule simultaneously absorbs two photons of lower energy to reach an excited electronic state. This phenomenon has ...

This image depicts the structure of the proposed organic molecule, alongside the energy level diagrams of two-photon absorption (left side) and thermally activated delayed fluorescence (right side).

Researchers at Kyushu University have developed a novel organic molecule that simultaneously exhibits two highly sought-after properties: efficient light emission suitable for advanced displays and ...
