Thermally stimulated exo-electron emission (TSEE) and thermally stimulated desorption (TSD) methods were employed to characterize interactions in the surface of thin films of Lu2O3 doped by Eu3+ fabricated by pulsed laser deposition. Samples with 1 and 3% doped europium were selected. Pulsed laser annealing (PLA) was performed to modify surfaces. TSEE maxima are shown at temperature ranges T ~120, 270 ◦C and T ~250, 350 ◦C for 1 and 3% europium content, respectively. The TSEE maxima correspond with TSD maxima of LuO and EuO observed at higher temperatures. At lower temperatures the release of atomic oxygen Oat and OH radicals is taking place at the points, edges, and other imperfections of the crystals.
