The technique of liquid phase epitaxy has been used to produce single-crystal garnet phosphor screens for cathode ray tubes. The films were rare-earth-doped yttrium aluminum garnets (YAG's) grown onto YAG substrates using a PbO:B/sub 2/O/sub 3/ flux. We have studied the light output of these layers as a function of film growth temperature, rare-earth activator concentration, and incident power density. With Ce:YAG layers it was possible to use beam power densities up to 10/sup 8/ W/m/sup 2/ and this produced a radiance of over 10/sup 5/ W/cm/sup 2/ sr.
