Abstract

We evaluated optical and scintillation properties of a Cr 0.5%:Y ₃Ga₅O₁₂ (YGG) and Cr 0.5%:Y₃Al ₅O₁₂ (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⁺ ²E→ ⁴A₂ and ⁴T→⁴A₂ transitions.
