Our collaborators at Sandia Labs led the demonstration of strong Purcell enhancement at telecom wavelengths afforded by spinel Fe3O4 nanocrystals with size-tunable plasmonic properties. 

Magnetite Fe3O4 is known for its magnetic properties, but at the nanoscale, it can also support a localized surface plasmon and contribute to applications in nanoplasmonics from information processing and telecommunications to light-based sensing.
