Paper Title:
XPS Study of In Situ One-Step Amination of Nanocrystalline Diamond Films
  Abstract

In the present work two different in situ amination of hydrogenated nano-crystalline diamond surfaces were studied. The effects of an UV irradiation in pure ammonia gas were compared to those produced in a mixture of pure ammonia gas with a small amount of pure oxygen. In situ XPS analysis was used to study the evolution of surface terminations from “C-H” to “CNH2”. As we will show in this work, the grafting of NH2 functional groups to the diamond surface is mediated by oxygen indicating that oxygen plays a crucial role in the process of amination.
