One of the important factors influencing the luminescence properties of a lasing ion is the crystal field of the surrounding. Optically active Er:LiNbO3 layers were fabricated by medium energy implantation under various experimental conditions. The Er+ ions were implanted at energies of 330 and 500 keV with fluences ranging from 1.0 x 1015 to 1.0x 1016 ion cm2 into LiNbO3 single-crystal cuts. The as-implanted samples were annealed in air and oxygen at two different temperatures (350 and 600°C) for 5 h. The depth concentration profiles of the implanted erbium were measured by RBS using 2 MeV He+ ions. The photoluminescence spectra of the samples were measured to determine the emission of 1.5 m. The concentration of the implanted erbium corresponds well with the fluence and is similar in all of the cuts of lithium niobate used. The intensities of the 1.5 m luminescence bands were different not only before and after the annealing but also in various types of the crystal cuts. The cut perpendicular to the cleavage plane 10–14 exhibited the best luminescence properties for all of the experimental conditions used. The influence of the annealing procedure on the recovery of the host matrix was examined by RBS/channelling.
