Gamma-rays are the most energetic form of light, with wavelengths far shorter than ordinary optical light (the light your eye can see), or even ultraviolet or X-ray light.
When a current is applied across the sandwich, the electrons and holes team up at the junction of the two materials and release energy in the form of light.
The Northern Lights happen when incoming solar radiation hits the earth's upper atmosphere and excites atoms to a new energy state, emitting colours which is energy in the form of light.
When the electrons cross the junction, they drop from the higher energy level to the lower one, and the energy each electron loses when it drops takes the form of light to a large extent.
It consists of 1, 000 tonnes of heavy water (the sort that has deuterium, a heavy form of hydrogen, in its molecules, instead of the normal, light form of the element).
ECONOMIST: The news that neutrinos have mass is both good and bad
The explosive energy is released in the form of neutrinos, light (mostly gamma-rays), and a pair of relativistically outflowing emitting jets.

The setting seems stark in the midday sun, but when the sun drops and the light shifts, a form of alchemy transforms the scene into one of sensual beauty.
This refraction eliminates both the red end of the spectrum (red light is not bent enough by the air layer to form part of the second image) and the blue frequencies (which are scattered away: this selective scattering is why the sky is blue).
Don Cowie also blazed into the stands as the hosts made light of their abject recent form.
The light does not form an image of the reacting molecules, but its interaction with those molecules specifically, which frequencies are absorbed, and how strongly allows Dr Zewail and his followers to work out how the molecules distort and reorganise themselves during the course of a reaction.
The team also showed how a large number of light pipes could be used to form a kind of dot matrix display.
Such bubbles form spontaneously, then expand at nearly the speed of light, within one might be another period of inflation, or non-inflation like what we observe.
Canon also plans to release a handful of accessories, including a few unique concepts for wearing the camera around your neck, playing off of the model's compact form-factor and light weight.
Captain Barry Fuller has returned to light training after being taken ill with a form of pneumonia.
The nastiest-looking arteries might be stabilized with some form of local therapy, such as drug-coated stents, light-activated drugs to kill off inflamed cells or even gene therapy.
There is a bright light on the horizon, however, in the form of Zetia, a new cholesterol medicine being sold by Merck and Schering-Plough.
This printing process is already used in organic solar cells and organic light-emitting diodes (OLEDs) that form the displays of mobile phones.
In other games, Russia needed a fortuitous 84th minute penalty to defeat Azerbaijan 1-0 in Moscow, Belgium continued their impressive form when beating Scotland 2-0 at home while Italy made light of losing Pablo Osvaldo to a red card after 46 minutes as they won 3-1 in Milan against Denmark .
