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.

通过电沉积在各种基底上生长ZnO纳米棒

研究了几种衬底上电化学生长的ZnO纳米棒的结构和光学性质。ZnO纳米棒是致密的，并且垂直方向上排列良好，并且基板的电阻率降低。扫描和透射电子显微镜结果表明，形成了直径在100nm至200nm范围内且长度约为600nm的六边形ZnO纳米棒。光致发光（PL）测量显示在382 nm处有很强的近带UV发射，而在600 nm处有较宽的带发射，这与深能级缺陷有关。
