Resumen:
Carbon-doped aluminum oxide (Al2O3:C) is one of the most used radioluminescence (RL) materials for
fiberoptic dosimetry due to its high efficiency (Andersen et al., 2010). However, it presents the drawback of
emitting in the spectral region, where the spurious radioluminescence of fibers is also important. In this
work, the radioluminescence response of rare-earth doped Al2O3 samples has been evaluated. The samples
were prepared by mixing stoichiometric amounts of aluminum nitrate, urea and dopants with different
amounts of terbium, samarium, cerium and thulium nitrates varying from 0 to 0.15 mol% (Barros et al.,
2010). The influence of the different activators on the RL spectra has been investigated in order to
determine the feasibility of using these compounds for RL fiberoptic dosimetry.
