ABSTRACT
Raman scattering (RS) spectroscopy enjoys broad application
in diagnostics of carbon-based materials. This method appears
particularly attractive because each allotropic form of carbon is
easily identifiable by its Raman spectra, is nondestructive, and
requires a small amount of material for analysis (in its confocal
version, the volume of the sample can be as small as 1 μm3).
When applied to analysis of detonation nanodiamonds (DNDs),
Raman spectroscopy can be used to advantage in determination
of the perfection of crystal structure, phase purity, and crystallite
size. The high quantum yield of luminescence of some impurity
centers embedded in diamond and their absolute photostability
have made nanodiamond (ND) one of the most promising materials
for fabrication of single-photon emitters and photoluminescent
biomarkers. This accounts for the pursuit of photoluminescent
properties of ND, including DND, having become a major goal in
present-day nanophotonics.
