摘　　要：珠宝市场上碧玺的充填现象十分常见,如何准确鉴别充填材料的种类一直是鉴定的难题。文章通过常规检测仪器、红外光谱、拉曼光谱和X射线能谱(EDS)来研究碧玺不同充填材料的鉴别特征。显微放大观察可以看到部分充填碧玺中有“闪光效应”和气泡、絮状充填物等特征,紫外线照射下部分充填碧玺裂隙处显示出蓝白色荧光。红外光谱测试中,所有碧玺样品在2851 cm^(-1)、2924 cm^(-1)和2961 cm^(-1)附近有C-H振动峰,证明所有样品经过有机物充填;拉曼光谱中3068 cm^(-1)、1610 cm^(-1)、1187 cm^(-1)和1114 cm^(-1)处的拉曼位移可以作为环氧树脂充填的鉴定依据。对充填碧玺裂隙进行EDS分析,所有样品的EDS图谱中均有很强的碳信号,证明充填物为有机物,面扫测试能进一步证明有机物充填在碧玺裂隙处。The filling treatment of tourmaline in the jewelry market is very common,and how to accurately identify the type of filling material has always been a difficult identification problem.This paper uses routine testing equipment,infrared spectroscopy,Raman spectroscopy and X-ray energy spectroscopy(EDS)to study the identification characteristics of different filling materials.Microscopic magnification observation shows that part of the filled tourmaline has“flashing effect”,gas bubbles and flocculent fillings,also the fissures show blue-white fluorescence under UV light.The infrared spectrum shows that all tourmaline samples have C-H vibration peaks near 2851 cm^(-1),2924 cm^(-1)and 2961 cm^(-1),it is proved that all samples are filled with organic matter,Raman shifts at 3068 cm^(-1),1610 cm^(-1),1187 cm^(-1)and 1114 cm^(-1)in the Raman spectrum can be used as the identification basis for epoxy resin filling.The EDS analysis of the filled tourmaline cracks shows that all samples have strong carbon signals in the EDS spectra.It is proved that the filling is organic.The EDS mapping test can further prove that organic matter is filled in the tourmaline fissures.
