中文摘要：

使用脉冲液滴注入式MOCVD,在金膜裹覆的MgO（100）衬底上于500℃合成氧化锌纳米针.纳米针为晶态并且在XRD谱线上主要呈现ZnO的4个衍射强峰（100）、（002）、（101）及（004）.金没有起到催化剂的作用,在较薄（2.4nm）金膜上生长的纳米针密度较高且直径较小.500℃是ZnO纳米针较佳的合成温度,在温度不低于550℃时合成的是片状ZnO.每周期前驱体的注入剂量对纳米针的形貌有显著影响.充足的注入剂量（6.8mg/周期）能够保证纳米针合成,而较低的注入剂量（3.4mg/周期）将会合成较短且直径较小的纳米针.

英文摘要：

ZnO nanotips were synthesized at 500 ℃ on the gold coated MgO（100） substrates by pulsed liquid injection metal-organic chemical vapor deposition（MOCVD）.The synthesized ZnO nanotips are crystalline with（100）,（002）,（101） and（004） as diffraction peaks.The gold films on the MgO substrates do not serve as catalyst and the thinner（2.4 nm） gold films make the nanotips in higher density and smaller diameter.The suitable synthesis temperature of ZnO nanotips is 500 ℃,but ZnO sheets are formed at the synthesis temperatures up to no less than 550 ℃.The injection mass per period has a strong effect on the morphologies of the synthesized products.Enough injection mass（6.8 mg/period） ensures the synthesis of ZnO nanotips,but lower one（3.4 mg/period） degrades the wires to be very short with smaller diameters.
