摘要

We report here the growth of dumb-bell like ZnO microcrystals via a simple chemical route. The X-ray diffraction (XRD) results show that the ZnO dumb-bell is crystalline in nature. The transmission electron microscopy (TEM) and scanning electron microscopy (SEM) studies reveal that the size of the dumb-bell is of approx1 (mu)m in length 500 nm in diameter. The photoluminescence spectra show a luminescence both in the uv and visible region covering green to red region of the electromagnetic spectrum. So this can be a promising material for light-emitting diode (LED) applications.
