Who discovered electroluminescence?
yeast
What is electroluminescence?
A phenomenon that causes certain materials to glow (without getting hot) when electrically excited.
Do neon lights get hot?
No it doesn't. It occurs through electroluminescence. Luminescence is light that occurs without heat. Elecroluminescence occurs when electrons in the neon gas get excited by the electricity thus producing light.

How does the ocean changes as you go deeper?
As depth increases temperature drops, water pressure increases and the eyes of sea creatures become more primitive. Electroluminescence plays a greater part in identification.
What is the cause of luminescence?
There are a few causes of luminescence, but one of the major causes is bioluminescent bacteria. They can be found independently or in a symbiotic relationship with organisms around the world. The other types are luminescence is chemiluminescence, electroluminescence, electrochemiluminescense, photoluminescense, thermoluminescence, and thermoluminescense.
What are some of the different types of luminescence?
Bioluminescence, chemiluminescence, crystalloluminescence, electroluminescence, photoluminesce and mechanoluminescence are all different types of luminescence. The terms are about different luminescence provenience, in the above other, biological, chemical, crystal, electrical, photo and mechanical.
Do neon lights get hot?
No it doesn't. It occurs through electroluminescence. Luminescence is light that occurs without heat. Elecroluminescence occurs when electrons in the neon gas get excited by the electricity thus producing light.
Only the sun and chemical changes produce light?
Only if you include heat (magma, meteors, light bulbs), charged particles (lightning, aurora) and electroluminescence (LED) under "chemistry". None of these produce light by what we normally think of as a chemical reaction.
How led lights work?
LEDs create light by electroluminescence in a semiconductor material. Electroluminescence is the phenomenon of a material emitting light when electric current or an electric field is passed through it - this happens when electrons are sent through the material and fill electron holes. An electron hole exists where an atom lacks electrons (negatively charged) and therefore has a positive charge. Semiconductor materials like germanium or silicon can be "doped" to create and control the number of electron holes. Doping is the adding of other elements to the semiconductor material to change its properties. By doping a semiconductor you can make two separate types of semiconductors in the same crystal. The boundary between the two types is called a p-n junction. The junction only allows current to pass through it one way, this is why they are used as diodes. LEDs are made using p-n junctions. As electrons pass through one crystal to the other they fill electron holes. They emit photons (light).
Why are LED lights better than incandescent light bulbs?
Light emitting diodes (LEDs) are semiconductors in a transparent epoxy casing. LEDs emit light through electroluminescence — that is, electrical current energizes electrons in the semiconductor material until the electrons emit a photon. Most of the electricity entering an LED is used to make light. It takes just 1.6 volts of DC current to light a single LED.
What radiates its own light?
Anything that gives off light can be said to radiate its own light. There are different types of light emission: incadescence, flourescence, chemiluminesence, and electroluminescence. Of all of these methods, only chemiluminescence is self contained - all other forms of light emission require an external source of energy. Only chemoluminescent materials, therefore, can be said to radiate their own light..Glow sticks are an example of chemoluminescent materials. Two chemicals in the stick are kept separate by a membrane. When the stick is bent sharply, the membrane ruptures, and allows the two solutions to mix and interact, thereby creating a chemoluminescent reaction..Bioluminescence is a naturally occurring example of chemoluminescence. Fireflies have light emitting organs that combine an enzyme (luciferase) with a pigment (luciferin), and the combination of these chemicals results in a chemoluminescent reaction..One could also argue that the sun, and all stars, are also self contained, and they therefore also radiate their own light.
What is the antonym for example?
There is no antonym for example, you can't have no example. Therefore there is no antonym for example.
