Fluorescent materials are used in illumination, displaying, solid state lasers,light communication,light memory and so on.
Yes, fluorescent lamps may be powered by DC but they need a DC lamp controller instead of an AC ballast and starter. The DC lamp controller is more complex. I have a 12V lantern with fluorescent lamp tubes.
not possible, as visible light photons have less energy and ultraviolet photons need more energy. Energy can neither be created nor be destroyed. So by conservation principle ultraviolet photon as they fall on fluorescent material could give out less energetic light photons, but the converse is not possible.
It would depend on the wattage of the fluorescent tubes. As a rough estimate, you would need about 6-8 standard 40-watt fluorescent tubes to approximate the light output of a 1000-watt metal halide bulb.
A fluorescent screen is a surface coated with a phosphor material that emits visible light when struck by electrons. It is commonly used in cathode ray tubes (CRTs) and other types of electronic displays to convert electrons into visible light, allowing images or text to be displayed.
not all incandescent lamps (bulbs) can be replaced by fluorescent lamps because there are some applications where there is no acceptable or equivalent fluorescent lamp. In some cases, other technologies may be useful--HID or LED lamps. There are some applications where the incandescent source, especially the tungsten-halogen type, still rules.
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.
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.
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.

Fluorescent materials are typically illuminated with ultraviolet (UV) light. When UV light is absorbed by the fluorescent material, it re-emits visible light at a longer wavelength, creating the characteristic fluorescence.
The interior of fluorescent light tubes are coated with a phosphor material. When this phosphor material is excited by ultraviolet light produced by the electric current passing through the tube, it emits visible light, creating the glow that we see.
fluorescent
The fluorescent microscope only views light of wavelengths equaling the fluorescing material that's being studied. If you have a dark background, cells and their structures can be glowing when seen.
Fluorescent material absorbs ultraviolet radiation and re-emits it at longer visible wavelengths, producing a glowing effect. This phenomenon is called fluorescence, where the material appears to radiate light of a different color than the ultraviolet light initially absorbed.
You need to purchase a Fluorescent dimmer switch, no circuit can dim the brightness of the light safely.
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.
