Optical constants of Ho films
Ho film optical constants were obtained in situ in the 3–1340 eV range from transmittance measurements performed at room temperature. Holmium films were deposited onto 5nm thick carbon films supported on a Ni grid. The refractive index n was obtained with KK analysis over an extended spectral range. Experimental data show that Ho is a promising candidate for transmittance filters and reflective multilayers in the EUV range.

The optical constants n and k of holmium (Ho) films were obtained in situ in the Visible-soft x-rays spectral range. Holmium films were deposited onto 5nm thick carbon films supported on a Ni grid. The extinction coefficient was obtained from transmittance measurements performed at room temperature; the refractive index n was obtained with KK analysis over an extended spectral range. Experimental data show that Ho is a promising candidate for transmittance filters and reflective multilayers in the EUV range. Good consistency of data resulted from the application of f and inertial sum rules. |
