采用磁控溅射的方法，在单层胶体晶体模板上合成了具有六方周期性排列的 Co 类空心球纳米阵列，并对其结构和光学性能进行了表征和测试。其光学吸收峰与类空心球壳结构的几何参数密切相关：如随着类空心球尺寸的变化，可以实现吸收峰位在几百纳米内的大范围调节(770~1270 nm)；而球壳厚度的变化，又可以实现吸收峰位在几十纳米内的精细调节。类空心球结构的周期及球壳厚度，可以通过选择适当的胶体晶体模板(600~1000 nm)及磁控溅射沉积时间来调控。该结构及其特殊的光学性能使其在光学器件、光子晶体及传感器等方面具有重要的应用前景。

Co nanoarrays with Periodic hexagonal structure is prepared by magnetron sputtering technology based on colloidal crystal monolayer template,the morphology and the optical properties are measured.The optical absorption peak depends on the geometry parameters of hollow sphere structure,the absorption peak can be tuned in large scale (770-1 270 nm)by changing the size of hollow sphere,and also fine-adjusted by changing the thickness of hollow sphere.In addition,the size and thickness of hollow sphere can be tuned by selecting suitable colloidal crystal templates (600-1 000 nm)and controlling the time of deposition.This structure and its unique optical properties may have potential applications in optical device,photonic crystal and sensors.
