Abstract

Luminescent screen suitable for use, for example in cathode-ray tubes, electron microscopes, electron spectroscopes and for forming pictures in X-ray image intensifiers. The luminescent screen comprises a self-supporting monocrystalline body including a luminescent layer containing at least one activator. Preferably the luminescent surface portion 5 is grown on the substrate portion 4 by liquid phase epitaxy or formed by activators diffused into a monocrystalline body. The screen is exemplified by garnets of Y, Ga, Gd and Al activated by Tb, Tm, Eu, Ce or Nd. <IMAGE>
