Title (EN) UV PHOTOBLEACHING OF GLASS HAVING UV-INDUCED COLORIZATION
(FR) PHOTOBLANCHIMENT PAR UV DE VERRE AYANT UNE COLORATION INDUITE PAR LES UV
Abstract: front page image
(EN)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 λC< 300 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 λB, wherein 248 nm ≤ λB ≤ 365 nm, to substantially remove the pink hue.
(FR)L'invention concerne un procédé de photoblanchiment par UV d'un échantillon de verre ayant une coloration induite par les UV. Le procédé comprend d'abord l'exposition de l'échantillon de verre à un rayonnement UV colorant ayant une longueur d'onde de coloration λC < 300 nm pour former le verre coloré, qui a une teinte rose. Le procédé comprend ensuite l'exposition du verre coloré à un rayonnement UV de blanchiment ayant une longueur d'onde de blanchiment λB telle que 248 nm ≤ λB ≤ 365 nm, pour éliminer en grande partie la teinte rose.
