Abstract: Hexagonal cone-shaped ZnO nanoparticles were synthesized by the esterification between zinc acetate and alcohol with non-basic solution route. For the formation process of ZnO nanoparticles, no bases, surfactants, or catalysts were used. Transmission electron microscopy (TEM), selected area electron diffraction (SAED), and scanning electron microscopy (SEM) measurements were used to investigate the morphology and structure. The synthesized ZnO nanoparticles were singlecrystal with hexagonal phase. Furthermore, the as-prepared ZnO particles showed a strong UV emission at 378 nm due to the annihilation of excitons, indicating that the ZnO nanostructure was promising as a high-performance optical material.

Key words: ZnO nanoparticle, Hexagonal cone shape, Photoluminescence property
