When the excited atoms relax back into their ground state, a low-intensity glow is emitted, giving the technique its name.

The requirement for samples of glow discharge atomizers is that they are electrical conductors.

The gas ions are accelerated towards the cathode and, upon impact on the cathode, sputter cathode material that is excited in the glow discharge to emit the radiation of the sputtered material, i. e., the element of interest.

Armfeldt's country estate is bathed in the golden glow of perpetual summer sunset at this high latitude (" Night Waltz One and Two ").

If an evacuated glass tube is equipped with two electrodes and a voltage is applied, the glass opposite of the negative electrode is observed to glow, due to electrons emitted from and travelling perpendicular to the cathode ( the electrode connected to the negative terminal of the voltage supply ).

However, a sufficiently sensitive radio telescope shows a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object.

This glow is strongest in the microwave region of the radio spectrum.

The glow is very nearly uniform in all directions, but the tiny remaining variations show a very specific pattern equal to that expected of a fairly uniformly distributed hot gas that has expanded to the current size of the universe.

* Electric Indigo is sometimes used as a glow color for computer graphics lighting, possibly because it seems to change color from indigo to lavender when blended with white.

The corona discharge glow at the surface of an object subjected to a high voltage electrical field is referred to as a Kirlian aura in Russia and Eastern Europe, however this should not to be confused with the paranormal concept of the aura.

The pink-orange glow running through the center of the tube is from the electric discharge which produces incoherent light, just as in a neon tube.

[...] There's one shot in particular, where Cruz enters a room in a greenish glow, which is right out of Hitchcock's picture.

Although the term phosphorescence is derived from phosphorus, the reaction that gives phosphorus its glow is properly called chemiluminescence ( glowing due to a cold chemical reaction ), not phosphorescence ( re-emitting light that previously fell onto a substance and excited it ).

A few curies ( 1 curie equals 37 gigabecquerels, 1 Ci = 37 GBq ) of < sup > 210 </ sup > Po emit a blue glow which is caused by excitation of surrounding air.

The visual sense is usually isolated by creating a soft red glow which is diffused through half ping-pong balls placed over the recipient's eyes.

When the sample is heated, at a certain temperature it will glow from the emission of electrons released from the defects, and this glow can be used to estimate the age of the sample to a threshold of approximately 15 percent of its true age.

This version of the screwdriver also appears, although never officially announced, to have a flashlight setting, as the Doctor is seen to have it emitting a continuous glow while not uttering the classic sonic noise.

In his 1967 spy thriller An Expensive Place to Die, Len Deighton misidentifies the Flemish coast tram: " The red glow of Ostend is nearer now and yellow trains rattle alongside the motor road and over the bridge by the Royal Yacht Club ..."

In practice, virtually all solid or liquid substances start to glow around, with a very dull red color, when no chemical reactions take place that produce light as a result of an exothermic process.

Ultraviolet radiation is invisible, but a small fraction of visible light passes through the filtering material, with wavelengths no longer than 400-410 nm, and as a result, when operating the lamp emits a dim purple or violet glow.

Although sky glow can be the result of a natural occurrence, the presence of artificial sky glow has become a detrimental problem as urbanization continues to flourish.

LPS lamp failure does not result in cycling ; rather, the lamp will simply not strike or will maintain its dull red glow exhibited during the start-up phase.

It is sometimes described as “ still emitting its own green glow ”, which would result in a rather complex optical illusion.

The visual result was a bluish glow around the puck.

Alcohol flush reaction ( also known as Asian flush syndrome, Asian flush, Asian glow, among others ) is a condition in which an individual's face or body experiences flushes or blotches as a result of an accumulation of acetaldehyde, a metabolic byproduct of the catabolic metabolism of alcohol.

Although mechanical in result, these transformations may have been magically instigated, as they occur instantaneously with an eerie glow and sound effect.

The result is that one lamp can provide a very soft, diffuse glow or quickly adjusted to illuminate an entire room, and everything in between.

It can cause chemical reactions, and causes many substances to glow or fluoresce.

Others include glow discharge, field desorption ( FD ), fast atom bombardment ( FAB ), thermospray, desorption / ionization on silicon ( DIOS ), Direct Analysis in Real Time ( DART ), atmospheric pressure chemical ionization ( APCI ), secondary ion mass spectrometry ( SIMS ), spark ionization and thermal ionization ( TIMS ).

Later on, researchers painted the inside back wall of the tube with a phosphor, a fluorescent chemical such as zinc sulfide, in order to make the glow more visible.

Poi can be performed in the dark to dramatic effect when spinners use poi containing a light source, such as UV-sensitive materials, LED lights, or chemical glow sticks.

* 1, 8-Diazafluoren-9-one, a chemical that makes fingerprints glow when lit by laser or blue-green light

As a parallel with the earlier Charles Knight-designed sleeve-valved automotive powerplants, any RCV sleeve-valved model engine that is run on model glow engine fuel using castor oil as a small percentage ( about 2 % to 4 % content ) of the lubricant in the fuel allows the " varnish " created through engine operation to provide a better pneumatic seal between the rotating cylinder valve and the unitized engine cylinder / head castings, initially formed while the engine is being broken in.

In an electroluminescent display ( ELD ), the image is created by applying electrical signals to the plates which makes the phosphor glow.

Ions can be created in an electric glow discharge.

Other activities for the crew included photography of the glow created as the shuttle's outer skin interacts with atomic oxygen in orbit and continued monitoring of protein crystal growth experiments in the cabin.

Several final observations of the Shuttle glow effect, a phenomenon created as atomic oxygen and other gases impact the spacecraft, were conducted.

The glow was created by bioluminescent dinoflagellates.

An overall glow is created by the black pastel not being completely opaque, allowing the paper to shine through.

The embers, ( graphite ) from the smokestacks would cause the cars and sidewalks to sparkle and created a golden glow throughout the night.

In recent days complete glow stick costumes have been created that attach to ones body, the two most popular being from Crayola and Glowstickables.
