The role of defects within the domain inversion process in ferroelectric LiNbO3 crystals was studied by investigating the optical properties of intentionally introduced Er3+ defect complexes. Drastic differences in the Er3+ emission were found using site-selective excitation-emission spectroscopy, which were due to a rearrangement of the defect complexes. The changes were used in a confocal luminescence microscope to image ferroelectric-domain structures.
