Summary

Story summary

Researchers at Kyushu University and Johannes Gutenberg University developed a molybdenum-based spin-flip emitter with a 130% quantum yield via singlet fission.
The emitter enables one photon to generate two excitons.
The breakthrough overcomes energy loss from Förster resonance energy transfer.
The team plans to integrate this technology into solid-state solar cells, LEDs, and quantum technologies, with findings published in The Journal of the American Chemical Society on March 25, 2026.
