Plasmonic color is an elegant color resulting from light absorption and emission induced by collective oscillation of free electrons in a metal and enables unprecedented new color expression. In particular, Al plasmonic color is highly desirable because of the low cost and high stability of Al. Here, we report a new cost-effective, wide-area fabrication method for an Al metal-insulator-metal (MIM) plasmonic nanostructure using a vapor deposition and sintering process.
等离子体激元颜色是一种由金属中自由电子的集体振荡引起的光吸收和发射所产生的优雅颜色，能够实现前所未有的新颜色表达。特别是，由于铝的低成本和高稳定性，铝等离子体激元颜色非常令人期待。在此，我们报道了一种使用气相沉积和烧结工艺制备铝金属-绝缘体-金属（MIM）等离子体激元纳米结构的新型经济高效的大面积制造方法。
