Abstract
The present invention relates to a process for ion irradiation of a particulate substrate containing the steps of embedding particulate substrate in a solid matrix having 10B atoms, and exposing the matrix obtained in the previous step to a neutron flux to give irradiated particulate substrate. The process is extremely effective and amenable to large scale and is particularly suitable for producing irradiated nanodiamonds and irradiated SiC particles.

A process for ion irradiation of a particulate substrate selected from diamond particles or silicon carbide particles, comprising the steps of:
- a. embedding particulate substrate in a solid matrix comprising 10B atoms;
- b. exposing the matrix obtained in step a) to a neutron flux;
- and
- c. dissolving the solid matrix;
- to provide irradiated particulate substrate.
A process for creating nitrogen-vacancy centers in diamond particles, comprising the steps of
- a. embedding diamond particles in a solid matrix comprising 10B atoms;
- b. exposing the matrix obtained in step a) to a neutron flux;
- and
- c. dissolving the solid matrix;
- to provide diamond particles with antisite-vacancy pairs.
A process of creating carbon antisite-vacancy pairs in silicon carbide particles comprising the steps of
- a. embedding silicon carbide particles in a solid matrix comprising 10B atoms;
- b. exposing the matrix obtained in step a) to a neutron flux;
- and
- c. dissolving the solid matrix;
- to provide silicon carbide particles with carbon antisite-vacancy pairs.
