To better understand the morphology and crystalline property of LSCO perovskite, highresolution transmission electron microscopy (HRTEM) is recorded. Particles are highly agglomerated and tend to form stacking on to each other. The crystals were heterogeneous in size, polydisperse, well crystalline and measured from around 80 nm in diameter, bigger than estimated from the XRD. The HRTEM image of perovskite is carried out to calculate the d spacing in the LSCO lattice. HRTEM image exhibited a lattice fringe spaced by 2.72 angstrom, corresponding to the (110) plane of LSCO (Figure ).
