Colloidal crystal materials have potential values in coding, sensing, displaying and so on. Attempts to promote these values tend to focus on the development of functional colloidal crystal materials with high color saturations and bright structural colors for practical applications. Thus, this work presented novel cuttlefish ink nanoparticles doped colloidal crystal particle material, which had distinguishable and high saturation colors, and could response to the electric field and pH obviously. It was also found that the doping could result in a short-range order and long-range disorder structure of the colloidal crystals, which endowed them with wide viewing angles. More importantly, by using electric field and ions dual-responsive hydrogel to replicate the composite colloidal crystals particles, the resultant cuttlefish ink nanoparticles doped inverse opal particles were imparted with the same high saturation vivid structural colors, as well as obviously structural color tunability. These features make the cuttlefish ink nanoparticles doped colloidal crystal particles ideal for many practical applications where structural color materials is needed.
胶体晶体材料在编码、传感、显示等方面具有潜在价值。为提升这些价值所做的努力往往集中在开发具有高色彩饱和度和明亮结构色的功能性胶体晶体材料以用于实际应用。因此，这项工作展示了新型的掺杂乌贼墨纳米颗粒的胶体晶体颗粒材料，其具有可区分的高饱和颜色，并且能对电场和pH做出明显响应。还发现掺杂会导致胶体晶体形成短程有序和长程无序结构，这赋予它们宽广的视角。更重要的是，通过使用电场和离子双响应水凝胶复制复合胶体晶体颗粒，所得的掺杂乌贼墨纳米颗粒的反蛋白石颗粒具有同样高饱和的鲜艳结构色以及明显的结构色可调性。这些特性使得掺杂乌贼墨纳米颗粒的胶体晶体颗粒非常适合许多需要结构色材料的实际应用。
