Bacterial Hybrid Light-Emitting Diodes. [PDF]
Adv MaterAbstractPhoton down‐converting filters with fluorescent proteins (FPs) are a new frontier in the quest for rare‐earth‐free and non‐toxic color filters for white light‐emitting diodes. There are, however, concerns related to the FP purification costs and lack of FP recyclability/reuse.

Josephson Light-Emitting Diode [PDF]
Physical Review Letters, 2010 We consider an optical quantum dot where an electron level and a hole level are coupled to respective superconducting leads. We find that electrons and holes recombine producing photons at discrete energies as well as a continuous tail. Further, the spectral lines directly probe the induced superconducting correlations on the dot.
