Abstract
A method for fabricating a luminant for a field emission display fabricated through PVD is disclosed. The method includes the steps of: forming a ZnO:Zn luminescent thin film on a glass substrate through PVD; and forming a conductive thin film on the ZnO:Zn luminescent thin film, to thereby change the luminescence threshold, brightness and luminescent color suitable for the operation characteristics of the emitter in a predetermined range, by controlling the thickness of the luminescent layer, temperature and ambient of heat treatment of the luminant.
