Abstract

Well-crystalline ZnO nanorods were synthesized by employing zinc acetate dihydrate and hydrazine hydrate as reactants without using any surfactant. The phase structure

morphology and optical properties of the product were characterized by X-ray diffraction (XRD)

scanning electron microscope (SEM)

high-resolution transmission electron microscope (HRTEM) and room-temperature photoluminescence (PL) spectrum. The results demonstrated that the well-dispersed wurtzite ZnO nanorods have an average diameter of 120 nm. The ZnO nanorods prepared by this simple solution method have a strong emission peak at 386 nm with a full-width at half maximum of 18 nm

and a wide emission band in the visible range. Without using any surfactant

microreactors for the nucleation and growth of ZnO nanorods were supplied by adjusting the ratio of the mixed solvents.
