摘要
合成蓝宝石与天然蓝宝石最为相似,如何区分他们,一直以来都是鉴定的难点.该文通过使用Senterra型激光拉曼光谱仪对天然蓝宝石、合成蓝宝石进行测试,分析其拉曼最强振动峰417 cm-1的半高宽.研究表明,天然蓝宝石的半高宽均大于4.60 cm-1,合成蓝宝石的半高宽小于4.60 cm-1.拉曼光谱半高宽的不同对鉴别天然蓝宝石与合成蓝宝石有重要的意义.
Identification of synthetic sapphire and natural sapphire has always been difficult due to their similarity. In this paper,Senterra laser Raman spectometer is applied to determination of the full width at half maximum（ FWHM） at the strongest vibration Raman peaks of 417 cm- 1of natural sapphire and synthetic sapphire. It is indicated that the FWHM of natural sapphire are all above 4. 60 cm- 1,the FWHM of synthetic sapphire are all below 4. 60 cm- 1. The distinguishment between FWHM of natural and that of synthetic sapphire is significant to the identification of natural and synthetic sapphire.
