التركية - الإنجليزية

تعريف fosforesan madde في التركية الإنجليزية القاموس.

phosphor

{n} a simple combustible substance of clear transparent yellowish color exhibiting a faint light in the dark

{n} the morning star

{i} substance that produces light when subjected to radiation

Any of various compounds of transition metals or of rare earths that exhibits phosphorescence

A chemical substance used in the production of selected stamps to activate machines that automatically cancel mail The machines react to the phosphor under ultraviolet light In 1959, Great Britain began to print phosphor lines on some of its stamps See also Tagging

A phosphorescent substance, such as zinc sulfide, which emits light when excited by radiation, as on the scope of a cathode-ray tube See phosphorescence

The special electrofluorescent coating used on the inside of a CRT screen that glows for a few milliseconds when struck by an electron beam Because the illumination is so brief, it must be refreshed constantly to maintain an image

The planet Venus, when appearing as the morning star; Lucifer

is a material which is capable of emitting light It is used in fluorescent lamps, monitors etc The duration of the emission depends on the type of phosphor

Substance which glows when struck by electrons The back of a cathode ray tube face is coated with phosphor

(n ) A red, green, or blue dot that makes up a pixel See also luminance

- A material which when excited with ultra-violet light emits a bright light

Phosphorus

A substance that emits light when excited by radiation

Stamps are overprinted, inked or impregnated with phosphorescent or 'fluorescent' substances for use in electronic letter-facing and postmarking machines

The material used inside a monitor to create the display An electron beam scans the inside of a monitor and the phosphor absorbs it in the form of light patterns

A chemical substance that fluoresces when excited by x-rays, an electron beam, or ultraviolet radiation Phosphors are composed of rare earth oxides or halides (e g , gadolinium, lanthanum, yttrium) and usually emit green light with decay times ranging from hundreds of nanoseconds to a few milliseconds

Element arranged in triads or stripes (depending on use of shadowmask or aperture grille) of Red, Blue and Green and situated on the inside surface of the CRT The phosphors glow their respective colours when hit by an electron beam, creating the on-screen image
