Colloidal photonic crystals were fabricated using polystyrene particles (180 nm) and PMMA particles (450 nm), respectively, with a new and simple self-assembly method without special equipment. SEM images indicate that the prepared samples have ordered structures with few defects. The position of the stop-band scale nicely agrees with the particles' size. The sintering process of the PS photonic crystal film was studied with AFM heating system.
采用新型简单的自组装方法，分别使用聚苯乙烯颗粒（180纳米）和聚甲基丙烯酸甲酯颗粒（450纳米）制备了胶体光子晶体，无需特殊设备。扫描电子显微镜图像表明，所制备的样品具有有序结构且缺陷较少。禁带位置尺度与颗粒尺寸吻合良好。利用原子力显微镜加热系统研究了聚苯乙烯光子晶体薄膜的烧结过程。
