This application features a method of forming a nanoporous layer. The method includes steps of dispensing on a substrate a colloid composition comprising a liquid and a number of nanoparticle clusters, and subjecting the dispensed colloid composition to drying to form the nanoporous layer over the substrate. The nanoporous layer includes nanoparticles deposited to form a three dimensional network of irregularly shaped bodies. The nanoporous layer also includes a three dimensional network of irregularly shaped spaces that are not occupied by the three dimensional network of irregularly shaped bodies.
