1. A method of making a polarizer, the method comprising:
providing polarization structures located on a substrate, the polarization structures arranged in a pattern for polarization of light;
applying an uncured fill layer on top of the polarization structures and extending into channels between the polarization structures, the uncured fill layer being a solution including molecules in a solvent, the solvent including water and an organic liquid, the molecules including metal atoms bonded to reactive groups, where each reactive-group is independently —Cl, —OR1, —OCOR1, or —N(R1)2, and R1 is an alkyl group;
chemistry of the uncured fill layer and chemistry of a surface of the polarization structures are attractive to each other; and
reacting the molecules to form a solid of the metal atoms interconnected with each other, defining a cured fill layer.
