Effect of Water Contained in Acetone on Nanocrystalline Diamond Particles or Film synthesis

Abstract

This paper describes a series of experiments to grow nanocrystalline diamond (NCD) in a closed system hot filament chemical vapor deposition (HFCVD) reactor using acetone containing various amounts of water. A commercial acetone includes a slight amount of water, so we tried to dehydrate from the acetone. Next, diamond was synthesized under the various type of water content. We investigate about an optimum acetone/water concentration ratio in diamond particle formation and film formation. We clarified the effect of water concentration on the morphology, nucleation density and size. The morphology, and grain size and structure of the diamond were examined with field emission scanning electron microscopy (FE-SEM) and Raman spectroscopy. We will refer to the synthesis process in detail about diamond and NCD.
