Abstract

Using zinc acetate dihydrate and sodium hydroxide as starting materials

ZnO nanorods with narrower size distribution were prepared via a H

-assisted hydrothermal process. The samples are characterized by means of XRD

FTIR

FESEM

HRTEM and SAED. The results show that the samples are single crystalline in nature. All of the nanorods have hexagonal cross sections and grow along the [0001] crystallographic direction. The room temperature photoluminescence (PL) measurement results show that the UV emission intensity at 390 nm of the as-obtained nanorods with H

increases significantly

while the green emission at 558 nm is suppressed. The addition of H

can modulate the nucleation and the growth rate of ZnO crystal.
