| Resumo: | Single crystalline SrTiO3 samples were implanted with Er ions of 150 keV at room temperature with fluences of 5x10(14) and 5x10(15) . Annealing treatments were carried out both in reducing and oxidising atmospheres to recover the implantation damage. Infrared 1.54 mum Er3+ luminescence between the two lowest spin-orbit levels I-4(13/2) --> I-4(15/2) as well as emission from higher excited states S-4(3/2) --> I-4(15/2) , F-4(9/2) --> I-4(15/2) and S-4(3/2) --> I-4(13/2) were observed in the implanted samples with highest fluence, annealed either in air or in vacuum. Multiple site location of Er3+ ion is discussed and compared with RBS/C and emission channelling results that indicate that Er goes to Sr and Ti sites. |
