摘要:
宝石业是泰国的重要产业之一，但大多数宝石并不完美且带有缺陷，常采用玻璃填充的方法来处理。但该方法填充的宝石含有有毒重金属，因此急需开发新的宝石改性技术。离子束是近来发展起来的新技术，可以用来处理玻璃填充的宝石并可以去除其含有的有毒金属。文中采用泰国本地的玻璃填充红宝石样品先经80 kV加速的氮离子束注入至1017 ions/cm2剂量，然后分别在泰国清迈和中国武汉用2 MeV和1.7 MeV的质子束做弹性背散射光谱分析。研究了离子束处理前后，玻璃填充宝石的金属杂质、含量及其分布。两地的分析结果互相印证、共同揭示了宝石中主要的有毒金属是铅，铅的浓度经离子束处理后约为0.15%，比离子束处理前降低了20倍，且铅在宝石中的分布是均匀的。结果表明：离子束是一种有效的处理玻璃填充宝石的方法。

Abstract:
Gemstone industry is one of the important Thailand local businesses. However, the majority of the stones are not perfect but with defects or flaws. Glass-filling treatment has been a traditional method to rescue the poor stones. Since the glass-filled stones may contain toxic heavy metals, development of new gemstone modification techniques is necessitated. Ion beams have been developed as a novel technique of modifying gemstones for gemological improvements and the technique is also being applied on the glass-filled gemstones to remove the toxic metals. Therefore, the glass-filled gemstones before and after ion beam modifications should be clarified for their metal impurity concentration and distribution. In this work, gemstone samples of local glass filled ruby were firstly by irradiated with 80 kV accelerated nitrogen ions to 1017 ions/cm2 and then analyzed using elastic backscattering spectrometry techniques with 2 MeV and 1.7 MeV proton beams in Chiang Mai (Thailand) and Wuhan (China), respectively. Both elemental concentration and distribution in the materials were analyzed before and after ion implantation. The results reveal that the dominating toxic heavy metal in the stone is confirmed to be lead. The atomic concentration of lead in the ion beam treated ruby is about 0.15% in a uniform distribution, decreased by near 20 times compared with that of the as-glass-filled stone, demonstrating the effectiveness of ion beam treatment of the glass filled gemstones.
