Abstract

See full text

A method of depositing a film comprising a monolayer of particles. The method includes providing a dispersion comprising particles and at least two liquids and depositing drops of the dispersion onto a substrate and evaporating the at least two liquids resulting in a film of a monolayer of the particles. One embodiment of the method includes a coating on the outer surface of particles such that the coating makes the particles substantially non-dispersible, substantially non-soluble and substantially non-suspendable in one of the liquids. A particulate film containing at least one layer of particles, wherein the at least one layer is substantially made of particles of a chemical composition and has uniform thickness. Optical devices containing a particulate film containing at least one layer of particles, wherein the at least one layer is substantially made of particles of a chemical composition and has uniform thickness.
