Abstract

Optical and scintillation properties of YVO₄, (Lu _0.5Y_0.5)VO₄, and LuVO₄ single crystals grown by the Czochralski (CZ) method with RF heating system are compared. All vanadate crystals show high transmittance (∼80%) in the 400900 nm wavelength range. In both photo- and radio-luminescence spectra, intense peak around 400500 nm, which was ascribed to the transition from triplet state of VO₄^3-, was clearly observed. The main decay time component was about 38 μs (YVO₄), 18 μs ((Lu _0.5Y_0.5)VO₄), and 17 μs (LuVO₄) under 340 nm excitation. The scintillation light yields of YVO₄, (Lu_0.5Y_0.5)VO₄, and LuVO₄ crystals (obtained from the ¹³⁷Cs excited pulse height spectra) were evaluated to be about 11,200, 10,700, and 10,300 ph/MeV, respectively.
