Patterned photonic crystals (PCs) have attracted considerable attention due to their great potential in practical applications. Direct writing is an important and convenient method to fabricate patterned PCs. However, due to the limited interaction among spheres and the evaporation of ink, the obtained patterns usually suffer from poor structure strength, and non-uniform and unstable structural colors. In this work, an in situ embedding and locking strategy for fabricating tough PC patterns in one step was demonstrated. With properly dried polymer films as “paper” and dispersions of CdS spheres as “inks” to write on the “paper”, the self-assembly of CdS spheres and locking of the PC structure can be achieved simultaneously, which gives rise to tough composite patterned PCs with uniform, stable and permanent structural colors. Based on this simple method, tough PC patterns can be easily and quickly created by direct hand writing or drawing without special treatment, equipment, masks or templates. The vivid structural colors of the tough PC patterns and this simple method show great potential for practical applications.

通过直接手写制作具有生动结构色彩的坚硬光子晶体图案

图案化光子晶体(PC)由于其在实际应用中的巨大潜力而​​备受关注。直接写入是制造带图案的PC的重要且方便的方法。然而,由于球之间的相互作用有限以及墨水的蒸发,所获得的图案通常遭受差的结构强度以及不均匀且不稳定的结构颜色的困扰。在这项工作中,一个原地演示了一种嵌入和锁定策略,可一步一步制造出坚韧的PC模式。通过适当干燥的聚合物膜作为“纸”,以及将CdS球的分散体作为“墨水”写在“纸”上,可以同时实现CdS球的自组装和PC结构的锁定,从而产生坚韧的复合材料图案PC,具有均匀,稳定和永久的结构颜色。基于这种简单的方法,无需进行特殊处理,使用设备,遮罩或模板,即可通过直接手写或绘图轻松而快速地创建坚硬的PC模式。坚韧的PC图案生动的结构颜色和这种简单的方法在实际应用中显示出巨大的潜力。
