New memristor-based artificial neurons emit light to enable denser, more efficient 3D AI chips, pointing to a future beyond ...

In a discovery that sounds like science fiction, researchers have shown that human brains emit flashes of light that can pass through the skull. These signals are so tiny and faint that they're a ...

Researchers at Kumamoto University have discovered that a purely inorganic crystal grown from water solution can emit circularly polarized light, a special form of light whose "handedness" ...

Human bodies are not quite as dark as they look. A growing body of research suggests that living tissue constantly releases an ultraweak glow, a stream of photons that appears to switch off when life ...

Researchers at Japan’s Chiba University have developed organic semiconductor devices that both emit light and harvest energy, ...

NHK’s Science & Technology Research Laboratories (STRL) says it has developed an organic light-emitting display element that can switch between emitting light and generating electricity, ...

This ETH Zurich logo consists of 2,800 nano light-emitting diodes and, at a height of 20 micrometres, matches the size of a human cell. A single pixel measures around 0.2 micrometres (200 nanometres).

A new one-step process miniaturises OLEDs to smaller than their emitted wavelength, enabling precise control of light direction and polarisation for displays, sensors and optical uses. (Nanowerk News) ...

Single crystals of potassium europium nitrate, K₃[Eu₂(NO₃)₉], grown from water by slow evaporation (a). Single-crystal X-ray diffraction reveals left- and right-handed chiral crystal structures (c, d) ...
