摘要
Defects induced by ArF UV-laser irradiation in the soda-lime silicate glass were studied by means of optical spectrophotometric and electron spin resonance measurements. The UV-laser induced defects in glass showed similar behavior to the X-ray induced defects. The defects of nonbridging oxygen hole centers attributed to two absorption peaks at 431 and 627 nm which were observed in the glass after the UV-laser radiation, The induced absorption increased when laser irradiation time or energy density increased. Our results demonstrated that the induced color in glass by UV-laser radiation could be bleached reversibly, which provides an alternative way to develop a recyclable colored glass.
