Abstract

Single-crystalline ZnO submicrometer rods have been synthesized by a simple hydrothermal method and characterized by means of X-ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), select area electron diffraction (SAED) and photoluminescence (PL). The results show that the as-synthesized product is pure-phase hexagonal wurtzite ZnO and the morphology of the ZnO is rod shaped with an average diameter of 0.8um and length of 10um. The room temperature PL spectrum of the ZnO submicrometer rods exhibits a strong blue emission at 440nm and three weak emission bands centered at 410nm, 467nm and 565nm, respectively.
