No.4（2009）12.Development of color drawing processes for diamond by Ion beam

Shohei Taniguchi, Takara Watanabe, Yukinori Saito

  In order to draw marks on a gem diamond, three processes using an ion accelerator were investigated. The results of trails using a 0.1mm pencil beam method, a photo-resisi method and a photo-resist and silver deposition method clarified that drawing with an ion beam is possible. The drawn marks were colored yellow-green, brown and black. Analysis by a laser Raman scattering spectroscope suggests that the diamonds were colored by deformations in the diamond crystal.
