Notes:
Erbium-substituted La1−xErxF3 lanthanum trifluoride epitaxial layers have been grown on Si(111) substrates by molecular beam epitaxy (MBE). Strong near-infrared luminescence, peaked at 1.54 μm, was observed from such films under electron beam excitation. This cathodoluminescence arises from the intra-4f-shell transitions 4I13/2→4I15/2 of Er3+(4f11). The infrared spectra reveal that MBE-grown LaF3 layers on Si(111) crystallize in the hexagonal tysonite structure, typical for bulk LaF3 single crystals.
