Abstract :
Epitaxial phosphor faceplates of cerium-activated yttrium aluminum garnet (YAG) phosphor (P-46) have been prepared on single-crystal YAG faceplates up to 3-in in diameter. Photolithographic reticulation of the faceplates was performed to increase the external efficiency of the epitaxial phosphor. A 1*1 in raster on a 2-in-diameter faceplate has produced a faceplate luminance of 62700 fL with a 40-kV excitation at an efficiency of 4.84 lm/W. This is 435 lm from a 1-in/sup 2/ raster at 90-W/in/sup 2/ excitation. Extrapolated performance of 2000 lm is expected from 3-in diameter (2.75-in-diagonal raster) faceplates.<>
