Glow in the dark

Science behind Glow in the dark

Glow in the dark is a number of different sciences, including: * The definition of photoluminescence from a molecular or atomic emission of electromagnetic energy has been absorbed: Examples include fluorescent and phosphorescent material. The dark plastic bag, your sign on the wall or ceiling is a glow stick products Photoluminescence example. * Light by living organisms use internal light emitted by a chemical reaction (that deep-sea biological) * Chemiluminescence is light and heat instead of as a chemical reaction (such as light sticks) of the total emissions emissions * Radiation emitting ionizing radiation is created by the bombing.

Chemiluminescence and photoluminescence is behind most luminous products. According to Alfred University, "and between the light emitting chemiluminescent obvious difference is the work of light emitting chemical by chemical reaction, emitting light in the photo release, but no chemical reaction.

Glow in the dark essentially by the contact surface, turns on 'black' goal, they focus on light-emitting materials. Interesting target, while they may be, or glow in the dark Halloween contact lenses require the same care you always reserves. Purchase of these medical supervision, with a valid prescription dark light contact and cleaning is for your safety and health importance.

Glow in the dark (History)

Phosphorus and its various compounds are phosphorescents or materials glow in the dark. I do not know what the P and its luminescent properties have been reported in ancient writings. The oldest known written opinion, also in China, dating back to 1000 BC on the Firefly and Firefly. In 1602, Vincenzo Casciarolo, found that phosphorus glowing "Bolognian Stone" is just the beginning for the first time in Bologna photoluminescence than scientific research.

Phosphorus was first isolated in 1669 by German physician Hennig Brand. Brand is an alchemist who is trying to change base metals into gold, when he isolation of phosphorus. All products contained in the dark photoluminescent phosphor powder. To make a glow in the dark toys, toy manufacturers are using the light and vitality through the normal, there is a very long persistence of phosphorus - the duration of light. Zinc sulfide and strontium aluminate phosphors are the two most commonly used

Excited state

Excitement is a rise in the level of energy of a physical system , a state over arbitrary reference energy, called the ground state . In physics there is a specific technical definition for energy level that is often associated with an atom is being excited to a higher energy excited state.

Electro Photon

The capture of photons caused (English Short for Electro Photonic Capture EPC) is to methodically study photon emission stimulated by electromagnetic fields of different subjects. For this we use visualization technology for landfill gas GDV (English, Gas Discharge Visualization) based on the Kirlian phenomenon, or Kirlian effect.

Chemical reactions

In the whole universe is subject to continuous development. From living up to the mountains or the stars, all due to a dynamic of change.

The reason for these changes continued to be sought ...
