Optical polaron formantion in cuo
WebThe optical properties of magnetite at room temperature were studied by infrared reflectivity measurements as a function of pressure up to 8 GPa. The optical conductivity spectrum consists of a Drude term, two sharp phonon modes, a far-infrared band at around 600 cm−1, and a pronounced mid-infrared absorption band. With increasing pressure both … WebDec 14, 2013 · The normal spectral emittance of α-Al {sub 2}O {sub 3} single crystal has been measured from room temperature up to the liquid state and from 20 cm {sup −1} up to 10 000 cm {sup −1}, in two polarization configurations. The spectra were fitted with a semi-quantum dielectric function model.
