Metastable defects induced by X-ray irradiation in Fe-doped soda-lime silicate glass
Source abstract
Abstract
Abstract Iron is the most important impurity in the commercial soda-lime silicate glasses. Defects induced by X-ray irradiation in the Fe-doped soda-lime silicate glass were studied by means of optical spectrophotometric and electron spin resonance measurements. The defects resulted in two absorption peaks at 610 and 425 nm which were observed in the Fe-doped glass after X-ray radiation. The induced defects were unstable at room temperature. The long-term fading of induced defects at 610 nm obeyed the first-order kinetics. The half-life time of absorption band at 610 nm for the base glass and Fe-doped glass were found to be about 8 and 20 years, respectively. The Fe-doped glass showed better long-term stability of induced color than the base glass.
