Detection of defects and their optical effects in diamonds

Abstract

In an attempt to create shallow NV centers in diamonds and study surface termination effects on them, a program was set up as follows.

  • All diamonds used in this study will be first analyzed prior to implantation to identify any luminescence regions.
  • A ‘dark’ region on the diamond surface will be identified where the implant should take place. Use a TEM copper mesh for location purposes.
  • Implantation using an ion implanter or accelerator.
  • Investigate surface termination effects on all implanted diamonds where NV- centers have formed as a result of the implantation.

This little talk is based on my visit to CSIR with an intention to perform bullets 1 & 2 above.
