摘要：
Certain example embodiments relate to a sunlight-scattering thin-film coating disposed on a substrate for greenhouse applications. The surface morphology of the coating promotes a better and more uniform light distribution. For instance, at least one thin-film layer disposed on a substrate may be textured so as to create surface features on the order of 0.1-5 microns, with the surface features being sized to cause (a) light having a wavelength of greater than or equal to about 800 nm incident thereon to primarily scatter to angles less than 30 degrees relative to a major surface of the substrate and (b) light having a wavelength of less than or equal to about 700 nm incident thereon to primarily scatter to angles greater than 20 degrees relative to the major surface of the substrate. This arrangement may advantageously direct beneficial light towards plant life while directing parasitic light away from the plant life.
