Brighter organic scintillators by hot exciton manipulation

Nature Photonics volume 18, pages 109–110 (2024)Cite this article

Subjects

The fast response and efficiency of plastic scintillators are severely degraded by the preferential population of slow triplet excited states in luminescence centres, such as in dye molecules. This issue can be solved by hot exciton manipulation, which avoids population of the lowest triplet state.
