摘要:

 通过便携式能量色散型X射线荧光(pXRF)、X射线衍射(XRD)、激光Raman光谱(LRS)等技术分别对天然绿柱石类宝石样品的化学成分、结构和物相进行了无损分析。同时,为弥补pXRF对轻元素测量上的不足,探索应用激光诱导击穿光谱(LIBS)对样品中的轻元素Be和Li进行了定性分析。根据XRD的分析结果,得到绿柱石单晶宝石样品的特征衍射峰晶面间距d=0.786 63、0.396 39、0.265 11 nm。对14件样品进行电子顺磁共振分析,在此基础上结合化学成分研究了Cr3+、V3+、Fe3+等离子的致色机理。同时,根据I型水、II型水的Raman光谱相对强度对样品中碱金属的存在形式进行了讨论。上述研究将为无损分析技术在珠宝市场中的应用提供参考信息。

 The chemical composition, structure and mineral phase of fourteen beryl group samples were analyzed by portalbe X-ray fluorescence (pXRF), X-ray diffraction (XRD)and laser Raman spectroscopy (LRS), respectively. To make up the insufficiency of the pXRF measurement, the light element (Be, Li) was qualitatively analyzed by laser induced breakdown spectroscopy (LIBS). According to the results of XRD, the characteristic diffraction peaks of single crystal beryl samples were around 0.786 63, 0.396 39 and 0.265 11nm. Combined with chemical composition, the coloration mechanism of Cr3+, V3+ and Fe3+ were investigated by electron paramagnetic resonance (EPR). According to the result of Raman spectra, the forms of alkali metal ions in samples were discussed by the relative intensity of I-type and II-type water. All these results can provide the useful information for the application of non-destructive techniques in jewelry market.
