摘要：
Graphene (GP) field emitters fabricated by the electrophoretic deposition (EPD) and their field emission performance can be enhanced and tailed simultaneously by chemical doping Au nanoparticles (NPs). It was found that doped Au NPs could both decrease the resistance of GP emitters and increase the density of field emission sites. The Au-doped GP emitters showed lower turn-on voltage, lower threshold field, higher field enhancement factor, higher luminance intensity, and emitting uniformity, compared with that of pristine GP. This study will provide us to further understand the role of doping effect on the GP emitters used for the future display. (C) 2013 AIP Publishing LLC.
