摘要:
A method for forming a light-redirecting article is provided wherein a surface of a substrate is conditioned by applying a layer of an embedment material. A close-packed layer of microspheres is assembled using drying-assisted self-assembly and applied to the conditioned surface. Microspheres are then embedded halfway into the surface of the layer of the embedment material.
