	Phosphor - Wikipedia, the free encyclopedia
		A phosphor is a substance that exhibits the phenomenon of phosphorescence (sustained glowing without further stimulus).
		Phosphors are transition metal compounds or rare earth compounds of various types.
		CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number.

	Phosphor and image storage panel - Patent 5198679
		The powdery phosphor may be processed in a conventional manner involving a variety of procedures for the preparation of phosphors such as a washing procedure, a drying procedure and a sieving procedure.
		In the method employing the stimulable phosphor having the formula (I) in the form of a radiation image storage panel, a radiation having passed through an object or radiated from an object is absorbed by the phosphor layer of the panel to form a radiation image as a radiation energy-stored image on the panel.
		The thickness of the phosphor layer varies depending upon the characteristics of the aimed radiation image storage panel, the nature of the phosphor, the ratio between the binder and the phosphor, etc. Generally, the thickness of the phosphor layer is within the range of from 20.mu.m to 1 mm, preferably from 50 to 500.mu.m.

		The optimum thickness of the phosphor layer for a given phosphor concentration is a compromise between efficiently absorbing the UV light (favoring an optically thick phosphor layer) and efficiently emitting visible light (favoring an optically thin phosphor layer).
		The brightest portion of the phosphor layer-where the excitation light is the strongest-now is exposed at the front of the device rather than being obscured through the thickness of the phosphor layer.
		The phosphor was mixed into the resin by first adding one-half of the phosphor to the resin and mixing it in by hand with a stainless steel spatula and then adding the other half and mixing it by hand.

	phosphor -- Encyclopædia Britannica (Site not responding. Last check: 2007-11-07)
		Ceramic phosphors are employed for both general lighting (as in fluorescent lights) and for electronic imaging (as in cathode-ray tubes).
		Phosphors function when electrons within them are stimulated from stable, low-energy positions to higher levels by an appropriate means—e.g., thermal, optical, X-ray, or electron excitation.
		A memory phosphor consists of a thin layer of material with properties that resemble those of TLD crystals in the sense that charges created by incident radiation remain trapped for an indefinite period of time.

	Luminescent article with high phosphor to binder ratio and manufacture thereof - Patent 5569530
		The coverage of the phosphor or phosphors present as a sole phosphor or as a mixture of phosphors whether or not differing in chemical composition and present in one or more phosphor layer(s) in a screen is preferably in the range from about 300 to 1500 g/m.sup.2.
		In the phosphor layer(s), any phosphor or phosphor mixture may be coated depending on the objectives that have to be attained with the manufactured intensifying or storage phosphor screens.
		In the preparation of the phosphor screen having a primer layer between the substrate and the fluorescent layer, the primer layer is provided on the substrate beforehand, and then the phosphor dispersion is applied to the primer layer and dried to form the fluorescent layer.

		Many efforts have been made to improve the luminance intensity, efficiency, and lifetime stability of phosphors at low-energy electron excitation, and the methods usually used are modifying the phosphor surface, controlling the activator concentration in the phosphor, and adding conductive material to the host material.
		Among those methods, preparing phosphor by conductor mixed into the host material is a more convenient method to enhance the luminance property of the phosphor, which increases the electrical conductivity of phosphor and prevents charge accumulation on the phosphor surface.
		Phosphors are synthesized by solid-state reaction at 1,200°C for 5 h.

	NRL - Protectively Coated Phosphors for Flat Panel FED Devices
		Surface degradation of the phosphor occurs due to reaction with residual gases in the vacuum, and this is exacerbated by the higher current density.
		The coated phosphor brightness decreases to only 60% of its original value, which is acceptable, compared with 18% for the uncoated phosphor.
		Even though our coated phosphor is acceptable for FED applications, we are now developing a double spraying process, whereby the coated phosphor is resprayed to fill in the initial nanoporosity.

	Alara, Inc - About Us - Storage Phosphor Technology
		Storage phosphors differ from phosphor screens used in conventional radiography in that rather than promptly fluorescing in response to x-ray exposure, they store a portion of the x-ray energy in the form of trapped electrical charge in the phosphor material.
		When an exposed storage phosphor imaging plate is irradiated with light of appropriate wavelengths, the trapped charges recombine, emitting visible light in the process.
		The concept of using of storage phosphors in medical imaging was first presented by Kodak.
