The disclosure provides methods and materials for preparing a titania nanoparticle product. For example, titania nanoparticle products having desirable optical properties such as a desirable refractive index are prepared according to the methods provided herein.

Synthesis of metal oxide, titania nanoparticle product, and mixed metal oxide solutions

Traditional solar control applications rely on thin metal films to reflect EM radiation with wavelengths longer than that of the visible spectrum. Unfortunately such films also block radiation in cellular, GPS, and radio frequency bands. In one aspect, the disclosure provides a selectively-blocking filter that uses one or more optical filters tuned to a specific range(s) of wavelengths (e.g. for blocking IR radiation), while readily transmitting other wavelengths (e.g. both visible light and cellular/GPS signals). The filters can be manufactured on both flexible and rigid substrates.

The disclosure provides materials, apparatuses, and methods for making multilayer coatings with a high degree of efficiency and control. In some aspects, for example, coatings are described having multiple layers of nanoparticles and a polyelectrolyte, wherein the nanoparticles form tightly packed monolayers. The interface between monolayers may include polyelectrolyte material. One or more aspects of such monolayers and interfaces are controllable.
