*3.2.2 HRTEM of Zn0.92Fe0.05La0.03O nanoparticles*

DMSs Zn0.92Fe0.05La0.03O (ZFLaO53) nanoparticles were synthesized by sol-gel process [21]. The value of nanoparticles size is 99 nm. The lattice spacing is calculated from high-resolution transmission electron microscopy (HRTEM) images (**Figure 4b**), which show that the distorted lattice has an enhanced interplanar spacing *d* [(101) planes] of 0.247 nm. It is also observed from HRTEM that some fractions within the lattice fringes are formed. This may due to some ferromagnetic clustered growth by dopants in Zn2+ lattice. The high crystallinity of the particles is evident from the selected area electron diffraction.
