SYNTHESIS OF MICRO- and NANODIAMONDS by the METHOD of OXY-ACETYLENE TORCH
Keywords:
micro-and nanodiamonds, oxy-acetylene torch, copper foil, Raman scattering of light, scanning electron microscopyAbstract
In this work are presented results of experiments on the synthesis of micro- and nanodiamonds by oxyacetylene torch on the surface of pre-deposited copper thin films. The influence of the thickness of the buffer copper film and the concentration ratio of oxygen and acetylene on the structure formation of the deposited samples was investigated during performed experiments. Studies by Raman scattering and scanning electron microscopy showed that the synthesis of micro- and nano-diamonds occurs under certain experimental conditions.
