| Abstract: | Spectroscopic properties of Lu 2 O 3 :Tb pellets sintered at 1000 v C or 1700 v C were investigated. The sintering temperature did not influence the optically excited emission and excitation spectra of the materials. However, the treatment temperature did influence the emission under cathode-rays stimulation. While the specimens sintered at 1000 v C showed only luminescent lines above 480 v nm resulting from a radiative relaxation of the 5 D 4 level, the samples heated at 1700 v C did show some luminescence in the blue region resulting from 5 D 3 M 7 F J emission. The blue emission could be recorded exclusively upon cathode-rays irradiation. |
