Abstract

This paper describes the experimental measurements of the optical properties ofpure liquid aluminum, zirconium, nickel and iron in the photon energy range 1 .2-3 .4 eV by pulsed-dye laser spectroscopic ellipsometry. The unique aspect of this study was the use of electromagnetic levitation to position and melt the specimens and thus eliminate any container derived impurities. This approach yielded extremely clean liquid metal surfaces on which spectroscopic ellipsometry was conducted. The complex dielectric functions were obtained on these liquids as a function of temperature and wavelength.
