This question can hardly be answered, please provide some more information. Do you intend to spin-coat a ZnO film? Drop-casting? Dip-coating? Without such additional infos, one can hardly help you!

Actually i want to spin coat the precursor solution on Si/SiO2 substrate. I generally used zinc acetate dihydrate as a precursor and ethanol as a solvent. But sometime solution was good and sometime not. I want some method which is reproducible.
