Abstract

Pr:LuAG single crystal has interesting properties of a higher density host (6.7g/cm³), high light yield (three times higher than Bi ₄Ge₃O₁₂(BGO)), a very fast 5d-4f emission decay time (∼22ns) and good temperature stability around room temperature. Recently we have developed single crystal growth of 2-inch-diameter Pr:LuAG with high uniformity of the light output and decay time on the whole crystal. In this work, we report the results of gamma-ray spectroscopy measurements performed using Pr:LuAG crystal by APD (Hamamatsu S8864-55). Pr:LuAG crystals, which were cut in a rectangular shape (2×2×15mm³) and mechanically polished, were used for all experiments. These samples were optically coupled to APD. Gamma-ray response have been evaluated in the range from 122 keV (152Eu) to 1.4 MeV (²⁴¹Am).
