Abstract
This invention is directed to a process for forming coatings comprising light metal fluorides on a substrate. More particularly, the coating comprising light metal fluorides is preferably made using sol-gel techniques and may comprise a concentration gradient of the light metal fluorides across the thickness of the coating to provide it with unique anti-reflective properties.
