Abstract

Bismuth tellurite single crystals, undoped and doped with 0.1% of Er atoms per mol of host during growth, have been investigated by ion beam methods. Despite the complex structure of the material axial directions with a strong channeling effect have been located and characterized. In addition the lattice location of Er was investigated using PIXE/channeling. The results indicate that erbium replaces bismuth in the lattice as expected for both being in trivalent valence state which is in agreement with previous results obtained by optical absorption spectroscopy.
