Figure 6
SEM images of the pristine La0.9 sample with different magnifications. A foam-like morphology and globular cavities can be seen in image (a). The structure formed during synthesis and was later crushed into smaller pieces during the grinding step. In image (b), more details of the crumbled pieces are visible at higher magnification. Image (c) displays a section of a cavity wall. While there are pores inside, the outside parts are denser. The thickness ranges from ∼230 to 500 nm. Very porous structures exist as well, as is shown in image (d) (a higher accelerating voltage of 20 kV was used for increased resolution). They are built up by crystallites of sizes around 60 nm, grown together and forming a network. |
