Optical Properties of Carbon from the Far Infrared to the Far Ultraviolet.
Abstract
Optical properties of carbon are studied in bulk state from (lamda) (TURN) 0.05 to 100 (mu)m for graphite, and from (lamda) (TURN) 0.05 to 1000 (mu)m for glassy carbon; in small particle state, the optical studies cover the spectral range going from (lamda) (TURN) 0.1 to 100 (mu)m for all the materials. A Kramers-Kronig analysis of near normal reflectance data and/or a reflectance data fit to a Drude-Lorentz model gave bulk optical constants. These optical constants are used in theoretical calculations of extinction and the results compared with experimental results obtained from measurements of a variety of carbon particles. It is inferred that the high experimentally observed extinction is mainly due to a shape effect.
