Using carbon-containing field-emission structures in cathodoluminescent light sources

Results of experimental and theoretical investigation of vacuum cathodoluminescent (VCL) light sources with field-electron emission from carbon-containing structures are presented. Comparative analysis of the distribution of current on the light-emitting anode surface in VCL sources of various designs has been performed. The influence of pulsed regime parameters on the VCL source brightness and efficiency has been evaluated. Promising directions in the development of VCL light sources based on planar-edge type field-emission structures are discussed.
