Wavelength-resolved TSL measurements after x-ray irradiation at room temperature were performed on undoped, Ce- and (Ce, Zr)-doped Lu₃Al₅O₁₂ crystals. Several glow peaks were observed in the 20-450^o C temperature region, whose intensities and emission spectra are influenced by doping. EPR measurements performed at 12K revealed typical spectra of Ce³⁺ (4f¹, S=1/2) occupying Lu3+ substitutional positions.
