Abstract

We evaluated optical and scintillation properties of a 0.03% Cr-doped Gd3Ga5O12 (GGG:Cr) single crystal grown by Czochralsk method for medical use. Since human body has low absorption region from approximately 700-1100 nm, near infrared scintillators would be applied to the real time dose monitor system. In the X-ray excited radioluminescence, the emissions related to 2E→4 A2 transitions of Cr3+ were observed at around 725 nm. The scintillation light yield of GGG: Cr 0.03% single crystal under 5.5 MeV alpha-ray excitation was determined to be 30% of BGO.
