Size and shape tailoring of ZnO nanoparticles
© 2016 Trans Tech Publications, Switzerland. ZnO nanoparticles were successfully synthesized via the co-precipitation method using zinc nitrate and sodium hydroxide as raw materials. Size and shape of ZnO nanoparticles were well controlled by varying the ratio of sodium hydroxide solutions (0.5-0.9...
