ABSTRACT:
There is disclosed a process for forming a photocathode having high quantum yield which comprises the first step of making a number of fine concavities and convexities in a surface of a substrate finished substantially in a mirror; the second step of blunting the fine concavities and convexities; and the third step of coating a photoelectron emissive material on the surface of the substrate.
