Effect of pH on ZnO nanoparticle properties synthesized by sol–gel centrifugation
Source abstract
Abstract
ZnO nanoparticles were synthesized at different pH values by the sol‐gel method and centrifuged at 3000rpm for 30min. The ZnO powders agglomerate when synthesized in acidic and neutral conditions (pH6and7).FinepowderswereobtainedwhenthepHofthesolswasincreasedto9.Themaximumcrystallite size (25.36nm) of the ZnO powder was obtained at pH 9. The particles sizes of the ZnO synthesized between pH 6 and 11 were in the range of 36.65‐49.98nm. Ultraviolet‐visible analysis (UV‐vis) also demonstrated that ZnO synthesized from pH 8 to 11 has good optical properties with band gap energy (E g ) between 3.14 and 3.25eV.
