COATED ARTICLE WITH ANTI-REFLECTIVE COATING AND METHOD OF MAKING SAME

摘要

A substrate is treated so as to improve anti -reflection (AR) characteristic s of a resulting coated article. In certain example embodiments, a glass substrate may be treated via ion implantation to increase a refractive index (n) value in a surface region thereof. In other example embodiments, an inde x- graded coating (single or multi¬ layer) may be formed on the substrate. In both embodiments, an AR coating
