    Abstract: The invention relates to a method for producing a field emission layer (3), preferably for luminescent screen applications, according to which in order to improve the serviceable life and long-time stability, a mixture consisting of a polymer (11) and carbon nanofibers (4), which are hardened in a low-oxygen, in particular, oxygen-free atmosphere at temperatures greater than 2000° C., particularly greater than 2500° C., preferably, approximately 3000° C., are applied to a cathode electrode (8) assigned to a cathode (1), and the cathode electrode (8), together with the carbon nanofibers (4)/polymer (11) mixture is heated to a temperature ranging from 300° C. to 500° C., preferably from 380° C. to 480° C., in particular, from 420° C. to 450° C. in an atmosphere at least containing oxygen, e.g. air, a consequence of the oxygen results in a pyrolysis and/or to a hardening of the polymeric base (7), and at least a portion of the carbon nanofibers (4) is exposed over at least a portion of the spatial extension of the carbon nanofibers (4), particularly at least over a portion of the length of the carbon nanofibers (4), in particular, at least over half the length.
