Abstract
Nd-doped LuVO 4 single crystals were synthesized by the floating zone method and their optical properties including scintillation were evaluated. The synthesized Nd-doped LuVO 4 samples had a LuVO 4 single phase. The 1.0% Nd-doped LuVO 4 had the highest photoluminescence (PL) quantum yield (87%) of all the samples in the NIR range. The Nddoped LuVO 4 samples showed scintillation peaks around 900, 1060, and 1320 nm due to the electronic transition of Nd 3+ . Moreover, there was a strong correlation between the scintillation signal intensity and the X-ray exposure dose rate in the wavelength range from 900 to 1600 nm, and all the samples showed good linearity with a dynamic range from 0.006 to 60 Gy/h.
