Abstract
We report the growth and characterization of SrS codoped with europium and samarium ions. The material was grown on (0

1) MgO substrate, using solid-source molecular-beam epitaxy technique. We show that the film epitaxial planes conserved the substrate surface symmetry—cubic. X-ray diffraction results establish the epitaxial relationship as cube-on-cube (0
