    • The size determined by the x-ray appears to be consistently smaller than that determined by the TEM bright-field images. The reality is likely somewhere in between due to the difference in the nature of the techniques. The width of the x-ray diffraction peak is a good way to determine the crystal size when there is a fixed size with no lattice deformation and no strain. Error could arise otherwise, leading to an underestimation of the crystal size, and certainly the particle size since a particle may contain multigrains. While the TEM bright-field image is essentially a Fourier transform of the diffraction peaks, it is accurate for dilute case in determining the size of particles, but tends to overestimate the size when there is considerable overlap of different particles in space, particularly since the image was obtained via an average over the specimen thickness.
