New Applications of Efficient Phosphors

Abstract

Efficient phosphors are applied in X-ray intensifying screens, cathode-ray tubes and fluorescent lamps. The introduction of rare-earth phosphors has resulted in a drastic improvement of the performance of these devices. As far as X-ray imaging is concerned, all developments have focussed on an increase of the speed and resolution of the intensifying screens. For application in projection television tubes the phosphors should be able to stand high current densities. This condition is fulfilled by rare-earth based phosphors. In fluorescent lighting we see the introduction of new rare-earth based lamps with a high output in combination with an excellent colour rendition.
