| 摘 要： | 天然与合成宝石一直是宝石鉴定中的难题,而拉曼光谱的半高宽,即声子"寿命"可提供宝石是天然或合成的信息。论文利用BTR111-785微型近红外拉曼光谱仪对天然、合成红宝石进行测试分析,研究表明天然红宝石的半高宽均在10cm-1以上,合成红宝石的半高宽均低于10cm-1。

| Abstract: | The differentiation of natural and synthetic gems is still a difficult problem in gems identification. The full width at half maximum (FWHM) of Raman spectrum, that is the life-span of phonon, can provide valuable information about. natural or synthetic gem. Analysis of the natural and synthetic ruby was performed by BTR111--785 mini-Raman spectroscopy, and it was found that the FWHM of natural ruby is more than 10 cm(-1), withal the FWHM of synthetic ruby is less than 10 cm(-1). |
