[16p-B410-1] Emission Properties of La2Hf2O7 doped with Yb as a NIR-emitting Oxide Scintillator for the Remote Dosimetry System
Keywords:Near-Infrared-Emitting Oxide Scintillator, rare earth element
We developed La2Hf2O7 doped with Yb (Yb:LHO) crystal as near-infrared emitting oxide scintillator by Core heating method. Stopping power of Yb:LHO for γ-rays is superior to that of existing scintillator elements for remote dosimetry system used in high dose rate region, e.g. decommissioning of nuclear power plant. In this talk, we will report the results of investigation for Yb:LHO scintillator, including its composition and emission properties.
