| Abstract: | Large-quantity growth of ZnO nanorods is achieved by oxidation of Zn powders with catalystfree method. The products are characterized
using X-ray diffraction, scanning electron microscopy, transmission electron microscopy and photoluminescence spectroscopy.
The as-grown nanorods are structurally uniform with diameter ranging from 60 to 150 nm and lengths of up to 5–8 μm, and they
are single crystalline in nature with growth direction parallel to 0001]. Room-temperature photoluminescence spectrum of
the nanorods shows a strong and sharp UV emission band at 385 nm and a weak and broad green emission band at 495 nm. The vapor-solid
model is also proposed to explain the growth behavior of ZnO nanorods in our synthesis process.
