Which material lines the tubes of fluorescent lights and glows when exposed to UV light?
The material lining the tubes of fluorescent lights is called a phosphor coating. This coating is designed to emit visible light when excited by ultraviolet (UV) light produced by the electrical discharge within the tube.
How does electrical current produce light?
Different kinds of light use different mechanisms. Currently, the technologies used include incandescent lights, fluorescent lights, and LEDs.In an incandescent light (that's the most wasteful light), a current heats up a wire, until it glows.In a fluorescent light, the current excites atoms, i.e., it raises electrons to a higher energy level. When the electrons fall back, they emit light.I believe LEDs work on a similar principle, i.e., exciting the atoms; however, the material is solid instead of a gas.Different kinds of light use different mechanisms.

Why does the radium glows in the dark?
i think it's because of this fluro chemical.
What temperature is white heat?
White heat typically refers to the temperature at which a material glows white due to its high temperature, which is around 1,800 to 2,200 degrees Celsius.
What is the strip of material that glows in a light bulb called?
The strip of material that glows in a light bulb is called a filament. It is typically made of tungsten and emits light when an electric current passes through it, heating it up to a high temperature.
What kind of material lines the tubes of fluorescent lights and glows when exposed to UV light?
Phosphor is the material that lines the tubes of fluorescent lights and glows when exposed to UV light. This material emits visible light when excited by ultraviolet radiation.

Difference between fluorescent and phosphorescent material?
Fluorescent material immediately glows when exposed to ultraviolet radiation, that is it fluoresces. Phosphorescent material slowly absorbs and re-emits the radiation it absorbs. This enables phosphorescent material to absorb visible light spectra to "glow in the dark" at a later time.
What is the deference between incandescent and fluorescent lights?
An incandescent light uses electric current passing through a wire with a high resistance to current flow. That makes the wire very hot and it glows, producing the light. A fluorescent light uses electricity to charge a gas in a tube. The charged gas glows, producing the light. For the same amount of light, more electricity is needed in an incandescent light than in a fluorescent light, but developing and building fluorescent lights required more advanced technology than did incandescent lights.
What material lines the tubes of fluorescent lights and glows to UV Light?
Phosphor coating lines the inside of fluorescent light tubes. When the gas inside the tube is excited by electrical current, it emits ultraviolet (UV) light. The phosphor coating then absorbs the UV light and re-emits it as visible light, creating the glow from the fluorescent light.
Does fluorescent material glow under infrared light?
No, fluorescent materials typically do not glow under infrared light. Fluorescent materials absorb ultraviolet or visible light and then re-emit light at a longer wavelength, usually in the visible range. Infrared light is outside this range and does not stimulate fluorescence in these materials.
When is a mineral a fluorescent?
when it glows under ultraviolet light.
Can light be changed into energy?
Chemical energy (chem-lights and lightning bugs) electricity (through LEDs, fluorescent tubes, neon lights, lasers) and heat (the sun glows from heat, and so do light bulbs)
Why diamond glows in dark?
Some diamonds are fluorescent. This means that light enters the stone and the wave length is converted to a longer light wave. Not all diamonds are fluorescent. No diamond will 'glow in the dark' without first being exposed to a light source.
How do glowing dashboards glows?
There are lights inside it so when you turn it on it glows.
How energy can be changed into light?
Chemical energy (chem-lights and lightning bugs) electricity (through LEDs, fluorescent tubes, neon lights, lasers) and heat (the sun glows from heat, and so do light bulbs)
When a fluorescent light bulb glows what state of matter is it?
it is plasma , gas and liquid
