In this paper,the field emission cathode coatings of Hf and Ti-doped nano-diamond were prepared by theelectrophoretic method,and the morphologies and field emission characteristics of samples were characterized byscanning electron microscopy and field emission measurements respectively. The results indicated that the uniformityof the cathode coating became worse and agglomeration occurs with doping of metal Hf powder and Ti powder. Fieldemission studie showed that the incorporation of Hf-doped nano-diamond reduced the field emission characteristics ofthe coatings. Besides,the current density of field emission was increased after doping titanium. In addition,with theincreased of titanium,the luminance of the sample increased gradually and the uniformity became worse. Therefore,the analysis results further showed that the appropriate amount of Ti-doped nano-diamond improved the field emissionproperties. Finally,the field emission mechanism of Ti-doped nano-diamond coating was discussed.
