Size Controlled ZnO Nanoparticles Prepared by Water-in-Oil Microemulsion
ZnO nanoparticles were carried out by Microemulsion method in the presence of TritonX-100 (poly oxyethylene tert-octylphenyl ether) as a surfactant. X-100/n-hextnol/cyclohexane/ waterW/O microemulsion system was also determined. Zinc chloride (ZnCl2·2H2O) and ammonia (NH3·H2O) were used as raw materials. The results indicated that the formation of ZnO nanoparticles was confirmed, using X-ray diffractometer (XRD) and transmission electron microscopy (TEM). The results showed that the nanoparticle was exactly ZnO with wurtzite type crystalline structure and the size of nanoparticles is strongly affected by the ratio of water to surfactant(R). With the R value increase, the particles size became larger.
