X-ray irradiation on the soda-lime container glass

X-ray irradiation induced defects in the commercial soda-lime container glass were studied by means of optical spectrophotometer and ESR. The induced color might be applied to producing recyclable glasses. The nonbridging oxygen hole centers (NBOHCs) were mainly responsible for the irradiation induced absorptions at 431 and 627 nm of glass. The absorption at 305 nm was attributed to the trapped electron. The induced deep color can be kept for longer than 7 months, but can be almost bleached at 300°C for 20 min.
