Triplets electrically turn on insulating lanthanide-doped nanoparticles

Nature, Published online: 19 November 2025; doi:10.1038/s41586-025-09601-y

To turn on and obtain emission from lanthanide-doped insulating nanoparticles, an electrical excitation pathway coupling them to organic optical molecules to form nanohybrids is described, enabling tunable electroluminescence properties of LEDs fabricated from such materials.
