Tal salts with polyvinylpyrrolidone (PVP) followed by sequential calcinations [22]. Thin films of La0.five Sr0.5 CoO3- are obtained by the pulsed laser deposition (PLD) strategy [23]. 2.6. Characterization Methods The diverse phases in the prepared perovskites could be differentiated employing X-ray powder diffraction (XRD). Additionally, the structure of perovskite may be characterized using single-crystal XRD evaluation. Thermal analysis approaches which include thermogravimetry (TGA), differential thermal analysis (DTA), and differential scanning calorimetry (DSC) is usually utilized to test the thermal stability of your prepared perovskites. The diverse morphological characteristics from the prepared perovskites might be studied making use of scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Also, the surface area measurement with the ready perovskites is often carried out using surface area analysis (BET). Raman spectroscopy makes it possible for the determination of vibration modes in relation with molecular dynamics. Also, the surface chemical groups of the prepared perovskites can be identified working with Fourier-transform infrared spectroscopy (FTIR) and X-ray photoelectron spectroscopy (XPS). The frequency-dependent conductivity spectra are determined by utilizing impedance spectroscopy. 3.
