Luminescence is the emission of light from a material due to various processes such as electron transitions, molecular vibrations, or chemical reactions. It can be caused by the recombination of excited electrons with holes in a semiconductor material, by the relaxation of excited molecules to lower energy states, or by the release of energy during a chemical reaction.

Is luminescence a physical or chemical property?
Luminescence is a physical property that involves the emission of light from a material when it is exposed to certain stimuli, such as electricity or radiation. It is not a result of a chemical reaction, but rather a characteristic of the material's structure and properties.
What is the difference between fluorescence and luminescence?
Fluorescence is a type of luminescence that occurs when a substance absorbs light at one wavelength and emits light at a different wavelength almost instantaneously. Luminescence, on the other hand, is a broader term that refers to the emission of light from a substance without the need for high temperatures.
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 is the difference between incandescence and luminescence, and how do they differ in terms of light emission and energy efficiency?
Incandescence is the emission of light due to high temperature, such as in a traditional light bulb, while luminescence is the emission of light without heat, like in glow-in-the-dark materials. Incandescence is less energy efficient because it produces more heat than light, while luminescence is more energy efficient as it produces light without generating excess heat.
What is difference between process and mechanism?
A process is a series of actions or steps taken to achieve a particular outcome, while a mechanism is the part of a system that performs a specific function or operation. In simpler terms, a process is the overall method or plan, while a mechanism is the specific component that enables that process to work.
When was Luminescence - album - created?
Luminescence - album - was created in 2004.
When was Journal of Luminescence created?
Journal of Luminescence was created in 1968.
What is bio luminescence?
bio-luminescence is light produced by a living organism, such as a firefly
Is bio luminescence?
bio-luminescence is light produced by a living organism, such as a firefly
What actors and actresses appeared in Luminescence - 2011?

When was Luminous Luminescence in the Atlas Position created?
Luminous Luminescence in the Atlas Position was created in 2001.
What is the underline mechanism of light production?
The underlying mechanism of light production involves the release of energy by excited electrons as they return to lower energy levels within atoms or molecules. This process is known as luminescence and can occur through various mechanisms such as fluorescence, phosphorescence, and bioluminescence, depending on the system involved.
What are the release dates for Luminescence - 2011?
Luminescence - 2011 was released on: USA: May 2011 Colombia: November 2011
What is the ability to radiate light?
Luminescence.
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.
What is luminescence the ability to do?
make light chemically
