Abstract
A method for manufacturing a metal fluoride-containing organic polymer film includes forming an organic polymer film on a base body. The method includes exposing the organic polymer film to an organometallic compound containing a first metal, thereby infiltrating the organic polymer film with the organometallic compound. The method includes exposing the organic polymer film infiltrated with the organometallic compound to hydrogen fluoride, thereby providing a fluoride of the first metal in the organic polymer film.
