The radioluminescence, photoluminescence excitation (PLE) and emission (PL) spectra of the CeLu1, CeLu2 centers in LSO, LYSO and YSO are measured and discussed between 800 and 400 K with respect to the CeLu1 and CeLu2 features assignment and separation. The inlufence of yttrium concentration in Lu2(1-x)Y2xSiO5: Ce3+ on CeLu1, CeLu2 luminescence characteristics is demonstrated. Temperature dependence shows that with increasing yttrium content the onset of the CeLu1 and CeLu2 deay times decrease and CeLu1, CeLu2 delayed recombanation integrals incease shift to higher temperatures. The 5d1 theramally induced excited-state ionization of both CeLu1 and CeLu2 centers is confirmed and studied by purely optical methods.
