Refractive indices for amorphous carbon
Abstract
Refractive indices, obtained over the wavelength range 700-130 nm, are given for an amorphous carbon with optical properties intermediate between those of diamond and graphite. The solid is formed via direct condensation from a gaseous medium containing C, C2, and C3 as well as trace quantities of linear polyyne molecules. Small amorphous carbon particles exhibit a high albedo in the extreme ultraviolet as required by observations of VUV scattering and, in hydrogenated form, they have significant IR absorption at 3.3-3.4 microns.
