Diamond has lots of attractive properties: low emission work function, extremely mechanical hardness, chemistry inertness, etching resistance, and so on. With these outstanding properties, it has been widely investigated in the area of field emission. In this research, field emission performances from diamond powders coated with sliver has been studied. The motivation for the experiment is to gain further understanding of the possible mechanism of diamond field emission. Scanning electron microscopy, X-ray diffractometry, and Raman spectroscopy were employed in order to determine morphology, crystal orientation, and quality of diamond powder coated with sliver. Diamond powders coated with sliver are deposited on ITO glass using electrophoresis coating method, through a solution of powders in isopropyl alcohol. Sliver is created from nitrate and then it coat diamond powder in sonication condition, taking advantage of reducibility of dextrose. Diamond powders are of about 1μ m diameter. The scanning electron microscopy (SEM) image (Fig. 1) indicates the morphology of the diamond powders coated with sliver.
