摘　　要：水热条件下,金属锌片与不同的酸式磷酸盐反应,在金属锌片上沉积磷酸锌微晶薄膜,用粉末X射线衍射(XRD)、扫描电子显微镜(SEM)等技术分别对所得磷酸锌微晶薄膜的结构和形貌进行表征。结果表明,表面活性剂的类型对磷酸锌微晶的形貌有很大影响,酸式磷酸盐反应物不同,得到的磷酸锌微晶的形貌和物相也不同。Zinc phosphate microcrystal thin films were synthesized by the reaction of zinc foil with different phosphate sources via hydrothermal method. The microstructure and morphology of the as-prepared samples were characterized by SEM and XRD. The experimental results showed that the samples were mainly Zn2（PO4）（OH） when NaH2PO4·2H2O was used as reactant, while the samples were mainly Zn3（PO4）2·3H2O when Zn（H2PO4）2·2H2O as reactant. The addition of surfactants in the system had important effects on the morphologies of zinc phosphate microcrystals.
