Chemical solution route to synthesize claw-like ZnO nanorod array and its optical properties

Abstract

By using a low-cost and facile hydrothermal method, a peculiar claw-like ZnO nanorod array is successfully synthesized. The hydrothermal growth is done in an aqueous solution with equimolar zinc acetate (ZAc, Zn(CH₃COO)₂·2H₂O) and hexamethylenetetramine (HMTA, C₆H₁₂N₄). The obtained ZnO nanorod array is characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicate that the nanorods are high-quality monocrystals. The photoluminescence (PL) spectrum is performed to investigate the optical properties of this product.
