Phosphor data display

An already substantial and rapidly growing market for CRT phosphors and tubes is in the area of data displays, both alphanumeric and graphic, e.g., computer terminals and word processors. In spite of dramatic advances in other technologies, CRT s are still the most cost effective way to present information, and very likely always will be. Most data display tubes do not use rare earth phosphors because of their high cost, rare earth phosphors find use only when there is a compelling need for their special properties. At the present time, this is limited to the use of Eu3+ reds in tricolor tubes that use the same shadow mask principle as conventional color TV. [Pg.189]

Zn3(P04)2 Mn, which has an emission maximum at 635 nm, is used as a cathode-ray tube phosphor for data displays under the TEPAC number P27 and WTDS specification RE. It is produced by solid-state reaction between ZnO, MnC03, and H3P04 in an aqueous slurry. After drying, firing is carried out at 900-1150 °C for several hours in an open crucible [5.376]. [Pg.247]

Over the last decade both the speed and accuracy of data acquisition and the sensitivity of the LEED experiment have been significantly improved. In most structure determination experiments the LEED patterns are displayed on a phosphor screen. LEED I-V curves are then measured by photometric or photographic means. Fast data acquisition systems have been developed that record LEED patterns with video cameras interfaced to computers and generate I-V curves during the experiment./3,4/ The sensitivity of LEED is also being greatly increased with the development of instruments that can detect single... [Pg.26]
