I want to make thin film ZnO by sol-gel route,

i use zinc acetate dyhidrat (ZAD) as precursor.
i have made a sol from ZAD with ethanol as solvent and EDTA as stabilizer, but in fact this sol is failed to become sol ZnO,

so i want to ask about this,
is it can to make sol ZnO with use nanoparticle ZnO manufactured by factory with a special solvent (in this case, i know what the suitable solvent yet)?

thanks for this opportunity,
