Abstract
An ultraviolet light-resistant article that includes: a substrate having a glass or glass-ceramic composition and first and second primary surfaces; an ultraviolet light-absorbing element having a an absorptivity greater than 50% at wavelengths from about 100 nm to about 380 nm and a thickness between about 10 nm and about 100 nm; and a dielectric stack formed with a plasma-enhanced process. Further, the light-absorbing element is between the substrate and the dielectric stack. Alternatively, the light-absorbing element can include one or more ultraviolet light-resistant layers disposed within the dielectric stack over the first primary surface.
