Fig. 6

Interplanar spacing and crystallite domain size as a function of the treatment condition. The lattice spacing was evaluated for all sample conditions at the (1− 1 0) and (1 1 0) reflection [panel (a)], and at the (2 0 0) reflection [panel (c)]. Average crystallite domain sizes extracted from the peak widths are shown in b for the (1− 1 0) and (1 1 0) reflections, and panel d for the (2 0 0) reflection
