Abstract:
We have used different spectroscopic techniques to obtain a consistent
quantitative absorption spectrum of a sample of meteoritic
nano-diamonds in the wavelength range from the vacuum ultraviolet
(0.12um) to the far infrared (100um). The nano-diamonds have been
isolated by a chemical treatment from the Allende meteorite (Braatz et
al. 2000, Meteorit. Planet. Sci., 35, 75). Electron energy loss
spectroscopy (EELS) extends the optical measurements to higher
energies and allows the derivation of the optical constants (n & k) by
Kramers-Kronig analysis.
Description:
The data table contains the optical constants, i.e. the
wavelength-dependent complex refractive index, measured on a sample of
nano-diamonds which have been extracted from the Allende meteorite.
The data can be used for modeling the optical properties of
interstellar and circumstellar matter containing nano-diamonds.
