Abstract

A glass substrate is modified by enriching a surface portion of the substrate with a metal such that the refractive index of the surface portion is different from that of the unmodified glass matrix. The modified surface is then coated with a metal oxide film to produce durable articles in a variety of interference-type colors suitable for architectural use to control incident solar energy.
