The resulting product and method for producing a single crystal CVD diamond of pale blue / green fancy blue or pale Fancy

摘要

I discloses a process for the production of a CVD diamond material of pale blue / green fancy blue or pale fancy. (Additional irradiation post-treatment or after), the method, all diamond material comprising the step of irradiating electrons to the single crystal diamond material grown by CVD process, introducing isolated pores in the diamond material, irradiated diamond material fancy vacancy concentration [V _T] × path length L and has a path length L Zensoraana concentration and [V _T] such that the 0.36ppm · cm 0.072ppm · cm, at most, at least become pale blue / green fancy blue or pale such. I also disclosed a pale blue diamond of fancy. [Selection] Figure Figure 1
