Abstract: Low-temperature method for depositing ultra fine diamond (UFD) films by a simple wet chemical route is presented. The UFD is produced from detonation synthesis of explosive substances. These nano-sized diamond particles under specific conditions formed stable suspension with analogous properties as sols. The organic suspensions of UFD had low values of surface tension and could easily wet different substrates to form films by dipping technique. The surface of the substrates and the effects of the organic medium stimulated a structural organization. The action of different forces during wetting caused the desegregation of particles, which culminated in even distribution on the substrate. The spectral investigation in UV-VIS-IR region showed that the films had diamond-like optical properties. It was found that glasses became more transparent with these UFD coatings on them. Efficiency of cutting tools was also found to increase significantly with the use of UFD coating on them.
