UV PHOTOBLEACHING OF GLASS HAVING UV-INDUCED COLORIZATION

摘要

A method of UV photobleaching a glass sample having UV-induced colorization is disclosed. The processed includes first irradiating the glass sample with colorizing UV radiation having a colorizing wavelength of λ_C300 nm to form the colorized glass, which has a pink hue. The method then includes irradiating the colorized glass with bleaching UV radiation having a bleaching wavelength of λ_B, wherein 248 nm≦λ_B≦365 nm, to substantially remove the pink hue.
