Figure 10
Micro-FT-IR mapping results of YAC12H, in which a circular profile is used; (a) is the non-saturated image of the circular profile. (b) Is the result of knife edge experiment. The diameter of the laser beam is measured to be 422 μm. (c) Is the lattice of the Micro-FT-IR mapping points; (d) is the corresponding spatial distribution of the relative proton concentration. The proton distribution does not entirely follow the circular profile and it seems being elongated along the c-axis. (e) Shows the O-H vibration bands collected from the labeled mapping points.
