ZnO nanocombs with 25 μm comb teeth were synthesized by chemical vapor deposition (CVD) method. Experiments were carried out to investigate the influence of carrier gas flow rate and temperature on ZnO comb teeth growth. The growth mechanism was demonstrated according to the morphology of prepared nanocombs under different growth parameters. The experimental results showed that the intensity of green emission significantly increased when the ZnO nanocombs became thinner and longer. It attributed to much more hanging bonds and oxygen vacancy on the surfaces of comb teeth
