Abstract: A coated article includes a heat treatable (e.g., temperable) antireflection (AR) coating having four layers. The AR coating includes a layer adjacent the glass substrate having an index of refraction substantially matching that of the glass substrate, and having a compressive residual stress. In certain example embodiments, the coating may include the following layers from the glass substrate outwardly: stress-reducing layer/medium index layer/high index layer/low index layer. In certain example embodiments, depending on the chemical and optical properties of the high index layer and the substrate, the stress-reducing layer of the AR coating is selected to cause a net compressive residual stress and thus improve the overall performance of the antireflection coating when the coated article is heat treated.

Abstract translation: 涂覆制品包括具有四层的可热处理（例如，可回火）抗反射（AR）涂层。 AR涂层包括与玻璃基板相邻的层，其折射率基本上与玻璃基板的折射率一致，并且具有压缩残余应力。 在某些示例性实施例中，涂层可以包括从玻璃基板向外的以下层：应力减小层/介质折射率层/高折射率层/低折射率层。 在某些示例性实施例中，根据高折射率层和基底的化学和光学性质，选择AR涂层的应力降低层以产生净压缩残余应力，从而提高抗反射涂层的整体性能， 涂层制品进行热处理。
