Undoped single crystals of Lu3Al5O12 annealed in the reduced atmosphere or additively colored in Al vapors were studied at 4.2-400K by the time-resolved spectroscopy methods. The 3.15 eV emission, excited in the 3.4, 5.3, and 6.1 eV absorption bands and having a decay time of 3.14 ns at 10 K, was ascribed to the F+-type centers.
