Abstract

The structural and optical properties of electrochemically grown ZnO nanorods on several substrates were investigated. The ZnO nanorods were dense and vertically well-aligned with the decrease in resistivity of substrates. Scanning and transmission electron microscopy results showed that hexagon-shaped ZnO nanorods with a diameter in the range of 100 nm to 200 nm and a length of about 600 nm were formed. Photoluminescence (PL) measurement showed a strong near-bandedge UV emission at 382 nm and a broader band emission centered around 600 nm, which was related to deep level defects.
