ABSTRACT:
A process for producing a thin fluorescent film for electroluminescence includes the steps of heating a raw material, composed of a base material and an activator, within an enclosed type crucible so as to generate a mixed vapor, injecting the mixed vapor into a vacuum zone through means of an injection nozzle, projecting an electron beam into the injected mixed vapor so as to ionize the mixed vapor, accelerating the ionized mixed vapor by means of an electric field, and permitting the accelerated ionized mixed vapor to collide with a base plate so as to form a vapor-deposited film upon the base plate.
