Crystal-Chemical Features of Diamonds Implanted with Helium Ions

Crystal-Chemical Features of Diamonds Implanted with Helium Ions Abstract Implantation of high-energy helium ions into crystals of natural colorless diamonds colors them bright yellow, brown, or black, depending on the implantation dose. The nature of the induced fantasy color and crystal-chemical features of the implanted diamonds have been investigated by IR spectroscopy and Raman spectroscopy. It is established that the radiation effect of helium ions on the diamond crystal structure results in the transformation of nitrogen-vacancy centers in its bulk with the formation of new A-type color centers, as well as the formation of carbon nanoclusters with the sp2 hybridization of bonds (which is typical of graphite) in black diamonds. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crystallography Reports Springer Journals

Abstract

Abstract Implantation of high-energy helium ions into crystals of natural colorless diamonds colors them bright yellow, brown, or black, depending on the implantation dose. The nature of the induced fantasy color and crystal-chemical features of the implanted diamonds have been investigated by IR spectroscopy and Raman spectroscopy. It is established that the radiation effect of helium ions on the diamond crystal structure results in the transformation of nitrogen-vacancy centers in its bulk with the formation of new A-type color centers, as well as the formation of carbon nanoclusters with the sp2 hybridization of bonds (which is typical of graphite) in black diamonds.
