Characterization of CVD-Ce3+:LuAG thick film scintillators. (a) Cross-sectional SEM image of 14 μm-thick Ce3+:LuAG thick film scintillator grown on (100) YAG substrate (CVD-14). (b) Absorption spectra of the CVD-Ce3+:LuAG thick film scintillators with various thicknesses (CVD-1 to CVD-30) and reference Ce3+:LuAG single crystal (SC-1000). (c) Photoluminescence–excitation contour plot of CVD-20 and SC-1000. (d) Photographs of the Ce3+:LuAG thick film scintillators with various thicknesses (CVD-1 to CVD-30) and SC-1000 under room light.
