HEAT TREATMENT OF NANODIAMOND PARTICLES WITH CONTROLLED POWDER LAYER DEPTH

Abstract: luminescent diamond is made by creating vacancies in diamond grains and heat treating the diamond grains by controlling a thickness of the diamond grains on a substrate. the heat treatment may occur in a temperature range that does not burn the diamond grains, and the controlled thickness produces an even color change and/or promotes oxygen terminations on the diamond particle surfaces.
