We evaluated optical and scintillation properties of a Cr 0.5%:Y3Ga5O12 (YGG) and Cr 0.5%: Y3Al5O12 (YAG) crystals grown by the micro-pulling down method for infrared emission scintillators. In the photoluminescence and X-ray induced radioluminescence measurements, the emissions peaks of Cr: YGG were located in the longer wavelength than those of Cr: YAG. Radioluminescene spectrum of Cr: YGG had a broad peak at 716 nm related to Cr3+ E-2 ->(4)A(2) and T-4 ->(4)A(2) transitions.
