通过简单的水溶液水热法，在脉冲电镀Zn纳米晶的基础上制备了均匀的ZnS纳米棒阵列。特别地，在水热反应中采用低温（95°C）和短时间（lh）。ZnS纳米棒是沿沿着一定的Zn晶向生长的。通过用Zn板代替Zn纳米晶进行的对照实验在衬底上没有发现一维ZnS纳米结构。因此，提出了在水热过程中，脉冲电镀Zn纳米晶既充当反应物又充当种子的观点。理论上，只要可以在基板上脉冲电镀Zn纳米线，就可以在几乎任何原始基板上制备ZnS纳米棒阵列。具有高长径比的ZnS纳米棒阵列有望成为未来场发射器件的潜在候选者。
Via a simple aqua-solution hydrothermal route, uniform ZnS nanorod arrays were fabricated upon pulse-plating Zn nanocrystallines. Particularly, low temperature (95°C) and short time (1h) were employed in the hydrothermal reaction. ZnS nanorods were found to be grown along certain Zn crystalline direction. Control experiments which were performed by replacing Zn nanocrystallines with Zn plate found no one-dimensional ZnS nanostructure on the substrate. Therefore, it was proposed that pulse-plating Zn nanocrystallines acted as both reactant and seed during the hydrothermal process. ZnS nanorod arrays could be theoretically fabricated on almost any raw base plate as long as Zn nanocrystallines could be pulse-plated on the plate. The ZnS nanorod arrays with high length-to-diameter ratio were expected to be a potential candidate for future field-emission devices.
