Abstract
Self-supporting luminescent screens made by applying a releasing agent to the surface of a mechanical supporting structure, having the desired shape, which agent is bound with a binding substance that is volatile at the evaporating temperature of a luminescent screen material, the latter being then deposited in a layer by evaporation onto the prepared supporting surface, until the deposited screen layer reaches a desired thickness, and eventually separating and removing the produced luminescent screen from the supporting structure.
