title: Radioluminescence of rare-earth doped aluminum oxide.
abstract: Al(2)O(3):C is one of the most used radioluminescence materials for fiberoptic dosimetry due mainly to its high efficiency. However, this compound presents the drawback of emitting in the spectral region, where the spurious radioluminescence of fibers is also important. In this work, sintered samples of Al(2)O(3):C doped with Tb, Sm, Ce and Tm have been prepared by combustion synthesis and their radioluminescence responses have been evaluated. The influence of the different activators on the radioluminescence spectra has been investigated.
