Abstract: A window is disclosed that includes a base layer, a first layer disposed on the base layer, a second layer disposed on the first layer, and a third layer disposed on the second layer. Each of the first, second, and third layers include a first compound. When a ratio of an actual volume of a material to a total volume occupied by the material is defined as a packing density and the actual volume is defined by subtracting a void volume from the total volume, each of the first and third layers has a packing density of between about 75% to about 85% of a packing density of the second layer.
