摘要
Rare-earth activated oxide phosphors have application in high energy photoluminescent (plasma panels) and cathodoluminescent (field emission devices) flat panel displays. These phosphors are composed of a highly insulating host lattice with fluorescence arising from the 3d --> 3d, 5d --> 4f or 4f --> 4f transitions in transition metal or ran earth ions. Fabrication of complex host compositions Y2SiO5, Y3Al5O12, Y2O3, and BaMgAl10O27 along with controlled amounts of the activators (Cr3+, Mn2+, Ce3+, Eu2+, Eu3+, Tb3+, Tm3+) represent a challenge to the materials synthesis community. High purity, compositionally uniform, single phase, small and uniform particle size powders are required for high resolution and high luminous efficiency in the new flat panel display developments. This paper will review the synthesis techniques and present physical and luminescent data on the resulting materials. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
