Abstract
Nd-doped GdVO 4 single crystals were synthesized and their photoluminescence and scintillation properties were evaluated. The Nd-doped samples showed scintillation due to the 4f-4f transitions of Nd 3+ with peaks at around 900, 1060, and 1320 nm. In addition, we evaluated the relationship between the scintillation signal intensity and the X-ray exposure dose rate for dosimetric application. All the Nd-doped samples demonstrated high sensitivity with a dynamic range from 0.006 to 60 Gy/h.
