The observed graphene electroluminescence emits light in the mid-infrared range at a wavelength of 6.5 µm.
Notes on verification
Confirmed against CNRS press release and Nature paper (Abou-Hamdan et al. 2025); corroborated by multiple institutional pages and a follow-up conference abstract, but all sources trace back to the same research group and single study, limiting full independence.
