The hydrogen ion beam induced luminescence of gadolinium oxide Gd_2O_3 doped with 1% of holmium (Ho) and 1% of bismuth (Bi) was investigated. Degradation of the holmium related 549 nm ion beam induced luminescence line intensity during hydrogen ion irradiation was observed. Two different mechanisms of the ion beam induced luminescence degradation has been proposed: the first one related to the accumulation of ion induced target material damage and the second mechanism related to the target temperature growth during ion beam bombardment. The experimental method for separation of both mechanisms effects was proposed and demonstrated.

The purpose of this work was identification of luminescent lines occurring in natural carbonate-fluor-apatite (francolite) mineral. For identification of several rare earth ions occurring in natural francolite, the luminescence of rare earth ions was extensively studied in artificial mineral consisting of a pure francolite (not containing rare earth) of the composition Ca_{5}(PO_{4})_{3} (F,O):Ca_{5}(PO_{4})_{3} CO_{3} activated with Pr, Eu and Sm ions and then compared with the luminescence features observed in natural mineral.
