Optical constants of Sr thin films
 


  Extinction coefficient of Sr compared with literature data

The optical constants n and k of strontium (Sr) films were obtained in situ in the 6–1220−eV range from transmittance measurements performed at room temperature. Strontium films were deposited onto 5nm thick carbon films supported onto different grids. The refractive index n was obtained with KK analysis over an extended spectral range. Experimental data show that Sr is a promising candidate for transmittance filters and reflective multilayers in the EUV range.
