Abstract
Cerium-doped lutetium oxyorthosilicate (LSO:Ce) scintillator ceramics were fabricated by slip casting in a 9 T vertical magnetic field, followed by hot isostatic pressing (HIP) at 1650°C under 150MPa applied pressure. XRD and Electron Backscatter Diffraction (EBSD) mapping results reveal that the grains of the LSO:Ce ceramics are aligned along the [4¯02] crystallographic direction. The degree of texturing (Lotgering factor, f) of the ceramics was determined to be 0.28. Measurements revealed the in-line transmittance of the textured LSO:Ce ceramics to be 4.7 times that of the untextured ceramics, attaining a transmittance of 6.6% at 420nm (emission maximum).
