Abstract

Photoluminescence has been measured from 100 to 300nm epitaxial thin films of MnF ₂ prepared on Si(1 1 1) substrates and having α-PbO ₂ orthorhombic structural type. The dominant luminescence consists of a broad band peaking around 575nm with a gradual tail extending to longer wavelengths. Weak spectral line features are observed on the short-wavelength side of the main band and are associated with magnon sidebands of Mn ²⁺ excitons that are perturbed by Mg and Ca impurities. Of note is a blue shift (∼12nm) of these sidebands when compared to their positions in bulk MnF ₂. The shift can be associated with different crystal field for Mn ²⁺ ions in orthorhombic phase.
