TEM BFI (left) and lattice image (right) coupled with Fourier transform inset for relatively large (>30 nm) and spherical titanium oxide nanocondensates having various stoichiometries in sample 2 which was fabricated by PLAL under FR-mode and then dwelling in water for 1 week: a Ti2O3 with point defects and disordered domains as viewed in [151] zone axis, b TiO2 rutile in [111] zone axis showing {101} twin planes and dislocations half plane parallel toc and d Point-count EDX spectrum of the Ti2O3 and TiO2 particles in (a) and (b), respectively, showing varied Ti and O counts (40.3 at.% Ti and 59.7 at% O for the former, whereas 34.3 at.% Ti and 65.6 at% O for the latter) with Cu counts from supporting copper grids
