The photoluminescence and radioluminescence properties of Y3(Al0.99TM0.01)5O12 (TM = Ti, V, Mn, and Cu) single crystals were investigated. Single crystalline rods of approximately 5 mm diameter were grown by the optical floating zone method. The photoluminescence quantum yields of the obtained single crystals were 1.3–3.8%. Both the intrinsic luminescence of Y3Al5O12 (YAG) and the extrinsic luminescence due to each dopant were observed in the radioluminescence spectra. The radioluminescence decay times of YAG doped with either Ti, V, Mn, or Cu were in the range from 6.9 μs to 10.2 ms.
