Query: Spectroellipsometric and ion beam analytical studies on a glazed ceramic
  object with metallic lustre decoration   In this work recently produced and commercially available glazed ceramic
object with metallic lustre decoration was studied by using a spectroscopic
ellipsometer with rotating compensator. The thickness and metal content of the
surface lustre layers are determined by ion beam analytical techniques, i.e.,
Rutherford backscattering spectrometry and external beam particle-induced X-ray
emission and the results were utilized in the construction of multilayer
optical models for the evaluation and interpretation of the
spectroellipsometric measurements.
