Luminescence, energy transfer and defects creation processes were studied for the Ce 3+ ‐doped YAlO 3 and Lu x Y 1– x AlO 3 ( x = 0.3) crystals in the temperature range 4.2–300 K under selective photoexcitation in the energy range 3.5–11.5 eV. For the first time, defects creation spectra were measured and analyzed. Influence of the charge and ionic radii of co‐doping ions on the luminescence and defects creation efficiency was considered. The origin of the defects created and possible mechanisms of their formation were discussed. (© 2005 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
