Phosphor - Wikipedia, the free encyclopedia (199 words) |
 | 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 (6778 words) |
| 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. |
