摘要：由于天然的坦桑石较为稀少,价格昂贵,使得它的一些仿制品在市场上屡见不鲜。本文通过对外貌酷似坦桑石合成镁橄榄石、天然橄榄石、蓝宝石以及坦桑石的拉曼光谱(785nm)测定与研究,得到合成镁橄榄石与天然橄榄石都具有Si-O伸缩振动引起的特征拉曼位移820cm-1、853cm-1和961cm-1;坦桑石的拉曼光谱中具有由Si-O伸缩振动引起的特征拉曼位移866cm-1、923cm-1和1148cm-1;蓝宝石的拉曼光谱中具有Al-O振动引起的特征拉曼位移416cm-1和641cm-1对比其拉曼位移的位置和强度,可快速、有效鉴定坦桑石、合成镁橄榄石和蓝宝石。
Natural zoisite is a rare gemstone because of its rarity, therefore some counterfeits of zoisite exist on gemstone market. This paper was based on Raman spectra testing and analyzing of synthetic forsterite, natural peridot, sapphire, zoisite, it was found that the diagnostic Raman shifts 820cm^-1 , 853cm^-1 and 961cm^-1 belonged to stretching vibration of band Si-O existed in the Raman spectra of synthetic forsterite and peridot; The diagnostic Raman shifts 866cm^-1,923cm^-1 and 1148cm^-1 belonged to stretching vibration of band Si-O existed in the Raman spectra of zoisite; Whereas the diagnostic Raman shifts 416cm^-1 and 641cm^-1 belonged to vibration of band Al-O existed in the Raman spectra of sapphire. Contrasting Raman shifts and its intensity, zoisite, synthetic forsterite and sapphire could be identified quickly and effectively.
