Growth and scintillation properties of Nd-doped Lu3Al5O12 single crystals by Czochralski and micro-pulling-down methods
The Nd-doped Lu3Al5O12 (Nd:LuAG) single crystal was grown by the Czochralski (CZ) method. In XRC profiles, the full-width at half-maximum (FWHM) value was 58 arcsec, which was much higher than that of the mu-PD (194 arcsec). In photo and radio-luminescence spectra, the CZ grown sample showed strong emission peaks attributed to Nd3+ 4f-4f transitions in visible wavelengths longer than 400 nm. The Nd:LuAG grown with the CZ method showed light yield of 7900 photons/MeV, which is comparable with the standard EGO and energy resolution of 14% under Cs-137 gamma-ray excitation.
