Antireflection (AR) coatings allow increased substrate transmission and reduce surface reflection over a specific wavelength range. We proposed a blue-blocking (BB) AR coating that allows maximal visible-light transmittance while minimizing the transmittance of blue light, owing to selective absorption. Admittance diagrams of BB Cr2O3 / SiO2 coatings and traditional AR Ta2O5 / SiO2 coatings were shown to demonstrate that small absorption affects the reflectance much less than it affects the transmittance. Therefore, by controlling the degree of absorption, the lower residual reflection can be obtained by optimizing the thickness of different layers of the overall stacked structure. Coatings were fabricated using remote plasma sputtering to meet the requirements of low residual reflectance (<1.16 % ), high visible-light transmittance (exceeding 90%), and short-wavelength transmittance attenuation by ∼20 % . These promising results indicate that this type of BB coatings is a good candidate for vision protection applications, such as eyeglasses, desktop and mobile digital screens, and solar control films used in architectural glass.

基于Cr ₂ O ₃介质中选择性吸收剂的防蓝光抗反射涂层

抗反射（AR）涂层可增加基材的透射率，并减少特定波长范围内的表面反射。我们提出了一种蓝光阻挡（BB）增透膜，由于选择性吸收，该镀膜可实现最大的可见光透射率，同时又将蓝光的透射率降至最低。BB Cr2O3 / SiO2涂层和传统AR Ta2O5 / SiO2涂层的导纳图表明，小吸收对反射率的影响远小于对透射率的影响。因此，通过控制吸收程度，可以通过优化整个堆叠结构的不同层的厚度来获得较低的残留反射。使用远程等离子溅射制造涂层以满足低残留反射率（<1.16％）的要求，高可见光透射率（超过90％），短波透射率衰减约20％。这些令人鼓舞的结果表明，这种BB涂层非常适合视力保护应用，例如眼镜，台式和移动数字屏幕以及建筑玻璃中使用的阳光控制膜。
