Auroras occur when charged solar particles bash into Earth's magnetic field and funnel toward the poles. The types of atoms these particles hit determines the color of light emitted. When you purchase ...

A new light-emitting device has been developed in the laboratory of Ali Javey, professor of electrical engineering and computer sciences at Berkeley, and it may have a very bright future. The new ...

Scientists have demonstrated that negative refraction can be achieved using atomic arrays -- without the need for artificially manufactured metamaterials. Scientists have long sought to control light ...

Researchers have discovered a way to stop the quantum dance of atoms 'seen' by electrons in carbon-based organic molecules. This development will help improve the performance of light emitting ...

Over the past decade, organic luminescent materials have been recognized by academia and industry alike as promising components for light, flexible and versatile optoelectronic devices such as OLED ...

Carbon nanotubes can glow brilliantly when light is absorbed by a flat sheet of atoms acting as an antenna to direct that energy into the tubes. This breakthrough might help create future tiny ...

Since the discovery of quantum mechanics more than a hundred years ago, it has been known that electrons in molecules can be coupled to the motion of the atoms that make up the molecules. Often ...

Last week, a huge solar flare sent a wave of energetic particles from the Sun surging out through space. Over the weekend, the wave reached Earth, and people around the world enjoyed the sight of ...

For the first time, scientists know what aurora light displays on Mars could look like for Martian explorers. On Earth, the Northern Lights, or aurora borealis, are created when energized particles ...
