Infrared Scintillation Properties of Yb∶YAG Crystal
Infrared (IR) scintillation properties of Yb∶YAG crystals with different Yb3+ doping level were measured by using pulsed electron beam. At room temperature the light yield of Yb∶YAG crystal is high and decay time is long. The dependence of light yield and decay time on Yb3+ doped concentration and temperature were demonstrated, and concentration quenthing was observed. The scintillation properties of Yb∶YAG were still affected by crystal quality. These measurement results suggest that some Yb3+-doped crystals should be possible for application in medical imaging.
