Study of optical properties of lutetium polycrystals by the ellipsometric method
Abstract
The optical properties of polycrystalline lutetium were studied at room temperature. The optical constants were measured by the ellipsometric method using a spectral LED ellipsometer SPEL-7LED (Russia) in the spectral range of 277–1000 nm. Based on the measured values of the refractive index and absorption coefficient, the dispersion dependences of optical conductivity σ, reflectance R, and the real and imaginary parts of the dielectric constant ε₁ and ε₂, as well as the electron energy loss function Im(ε)–1, were calculated. It was found that interband electron transitions have a significant effect on the optical properties of solid lutetium. In the optical conductivity spectra of lutetium, two absorption bands are observed with maxima at photon energies of 1.86 and 3.11 eV, associated with interband transitions.
