1. A method for forming a ceramic-based material, the method comprising:
(a) depositing a composition comprising nanoparticles having at least one dimension less than 100 nm and an aspect ratio of 1.5 or greater, and a carrier fluid on a surface of a substrate to form an as-deposited layer of the composition, wherein the nanoparticles are selected from a group consisting of WO3, ceria, hafnia, titania, and combinations thereof, and further wherein the carrier fluid is an inorganic ionic liquid consisting of inorganic ions and having a melting point at or below room temperature; and
(b) sintering the as-deposited layer at a sintering temperature to form a ceramic-based material.
