    • Fluorine-doped antireflection coatings, methods for preparing the coatings and articles comprising the coatings are disclosed. The fluorine-doped antireflection coating comprises a fluorine-doped xerogel coating disposed on a substrate. The index of refraction of the xerogel coating is less than the index of refraction of the substrate, generally between about 1.15 and about 1.45. The fluorine atoms can be distributed uniformly through the thickness of the coating, disposed at the surface of the coating, or the distribution can be graded from the surface through the thickness of the coating. The methods comprise applying a coating precursor solution comprising a sol-gel precursor to a glass substrate, heating the coating to form a xerogel coating, and fluorine-doping the coating. The fluorine-doping can be performed by utilizing a coating precursor solution comprising a first fluorine source, contacting the cured coating with a second fluorine source, or a combination thereof.
    • 公开了氟掺杂抗反射涂层,制备涂层的方法和包含涂层的制品。 氟掺杂抗反射涂层包括设置在基底上的掺氟干凝胶涂层。 干凝胶涂层的折射率小于基材的折射率,通常在约1.15至约1.45之间。 氟原子可以均匀地分布在涂层的厚度上,设置在涂层的表面,或者分布可以从表面通过涂层的厚度分级。 所述方法包括将包含溶胶 - 凝胶前体的涂层前体溶液涂覆到玻璃基底上,加热涂层以形成干凝胶涂层,并对该涂层进行氟掺杂。 氟掺杂可以通过利用包含第一氟源的涂覆前体溶液,使固化的涂层与第二氟源接触或其组合来进行。
