A Multitechnique Study of Fluorinated Nanodiamonds for Low-Energy Neutron Physics Applications

Résumé

Data of quasi-specular reflection of cold neutrons, prompt-γ neutron analysis, X-ray Raman scattering (XRS) and neutron Pair distribution function (PDF) analysis with powder of detonation nanodiamonds are analyzed to collect their structural properties and chemical composition. Both as-synthesized and purified were studied using fluorination samples. Removal of both sp 2 amorphous carbon shell and hydrogen atoms is evidenced respectively by the change of neutron-nuclei optical potentials of nanoparticles and the increase of their neutron reflectivity. Moreover, sp 3 diamond cores of nanoparticles stay intact during the fluorination as revealed by similar scattering patterns, PDF and XRS data. Quasi-specular reflection, PDF and XRS data are complementary for the study of nanomaterials and in good agreement with conventional characterization techniques (infrared spectroscopy and solid-state NMR).
