High-color-purity,high-brightness and angle-insensitive red structural color

We propose a simple five-layer structure for creating red structural color, which has high color purity and high brightness.The design is based on the superposition of a silver substrate and multilayer silicon material. Absorption at the shorter wavelengths of the structure is effectively guaranteed, and reflection at the longer wavelengths is well enhanced. The red structural color has a peak reflectivity of 91% and a colorimetric purity of 0.9. Moreover, the designed structure displays angle-i...     

截止斜率可控的蓝光防护光学薄膜

为了减少短波蓝光对人眼的伤害,同时确保蓝光对人体节律的有益调节,精确控制400～500 nm的透射斜率在蓝光防护中尤为重要.本文提出非线性玻尔兹曼函数拟合长波通薄膜的方法,分别通过非线性及线性光谱目标值优化得到膜系结构(Z1)和(Z2).通过对比(Z1)和(Z2)薄膜的光谱和导纳图,分析可知经非线性目标值优化后的薄膜具...
