摘要

Single crystalline GaN-layers were implanted with radioactive ~(167)Tm and ~(168)Yb ions, and their lattice sites were determined using the emission channeling technique. After the decay of ~(167)Tm to ~(167)Er, photoluminescence studies were performed. Upon room temperature implantation, rare earth atoms immediately occupy relaxed substitutional sites with an average relaxation of about 0.025 nm. Isochronal annealing treatments up to 800 ℃ and co-implantation of oxygen to a dose an order of magnitude greater than that of the Tm or Yb do not influence the rare earth lattice sites. A variety of different rare earth related luminescence lines are observed, and co-implantation of oxygen strongly changes the line intensities.
