Researchers have developed a new way to make ultra-narrow band, near‑infrared LEDs by “electrically powering” materials that normally do not conduct, using attached organic molecules that act as molecular antennas. The work opens a path to highly precise light sources for deep‑tissue medical imaging, optical communication, and chemical or biological sensing. Core scientific breakthrough [...]
