phos·phor

(fos'fŏr),
1. A chemical substance that transforms incident electromagnetic or radiation energy into light, as in scintillation radioactivity determinations or radiographic intensifying screens or image amplifiers.
2. Any substance capable of exhibiting phosphorescence.
[G. phōs, light, + phoros, bearing]

phosphor

(fos′fŏr, ′for″) [Fr. phosphore, fr L. phosphorus, morning star, fr Gr. phōsphoros, light-bringer]
A substance that in radiographic intensifying screens, fluoroscopic image intensifiers, or other image receptors converts photons of ionizing radiation into light, thereby amplifying the image.

rare-earth phosphor

An element such as yttrium, gadolinium, or lanthanum, used for ultra-high-speed radiographic intensification screens.

4 Summary of eight-year forecasts for LED phosphors
Lightscape Materials is a private, US-based research company with intellectual property in specialty phosphor technology.
ChromaLit XT allows us to push the envelope when it comes to providing higher outputs for smaller lighting apertures incorporating remote phosphor technology," said Andrew Littler, Director of Vexica, an LED lighting solutions company.
This report covers the light emitting principle of phosphors used for LED lighting, manufacturing technologies thereof, and technologies for phosphor coating and phosphor layer formation.
Compared to conventional LED designs, where blue chips are coated with a phosphor compound, the ChromaLit Collection leverages a phosphor composite separated from a blue LED energy source.
The fundamental physics of these phosphors is compelling, and we are taking the next steps to assess their feasibility for commercial lighting by evaluating chemical issues and improving the synthetic procedures," says Steve Payne, a leader on the project.
Until 2008, Chinese LED packaging firms obtained phosphors primarily from imports alone.
A high luminous flux of white light was realized through the development of a phosphor material that is not subject to luminance saturation[2] even when irradiated with high-intensity laser light.
The ChromaLit collection implements precision optics manufacturing and Intematix's phosphor technology to provide lighting manufacturers with the capability to create lighting systems in any shape and color.
Intematix, a United States-based manufacturer of LED phosphors, has signed a comprehensive licensing agreement with Tridonic, a leading manufacturer of lighting components and part of the Zumtobel Group of Austria.
