Here, we report the effect of substrate, sonication process, and postannealing on structural, morphological, optical properties ZnO thin films grown in presence isopropyl alcohol (IPA) at temperature 30–65 °C by successive ionic layer adsorption reaction (SILAR) method both soda lime glass (SLG) Cu foil. The X-ray diffraction (XRD) patterns confirmed preferential growth along (002) (101) planes...
