X-ray irradiation induced color centers and silver atoms in silver-doped soda-lime silicate glass at room temperature. After natural solar irradiation, the intensities of induced absorptions were greatly decreased; and the induced color was much unstable than sample without solarization. The induced absorption band at 330 nm was disappeared after solar irradiation, because silver atoms dissolved into ions during solarization. (c) 2005 Springer Science + Business Media, Inc.
