Abstract
A conversion screen such as is used for X-ray image intensifier screens, X-ray image intensifier tubes, cathode-ray tubes, image pick-up tubes, X-ray electrography, fluorescent lamps and the like is formed by the deposition of a layer of conversion material on a carrier (19) via a melting space (7) which is preferably heated by means of a plasma arc. This method of deposition offers very robust screens with a high density and also allows the filling of recesses in a carrier with conversion material, so that structured conversion screens can be formed.
