Description
LSO:Ce, LYSO:Ce and GSO:Ce single crystal scintillator light emission
characteristics were studied in low γ-ray energy range (Tc-99m source) used
in nuclear medical imaging. The absolute luminescence efficiency and the
optical emission spectrum of the three scintillators was measured, under γ-
ray excitation using an integration sphere coupled to a photomultiplier and a
spectrometer respectively. Spectral compatibility of all scintillators to optical
sensors was also estimated. The absolute efficiency of all crystals was found
adequately high. Their emission spectrum was found compatible (70% -
95%) to most currently employed optical photon detectors.
