【摘要】 采用电子探针、X射线衍射仪、激光拉曼光谱仪、红外光谱仪对天然翡翠和染色翡翠进行综合对比研究,结果表明,X射线多晶衍射分析天然翡翠和染色翡翠的主成分均为硬玉;电子探针分析虽未检出染色翡翠中的致色元素,但天然翡翠和染色翡翠的背散射图像截然不同;经拉曼分析,染色翡翠则出现有机染料相似的荧光背景;红外光谱分析,染色翡翠在2800~3100cm-1范围内出现强烈的吸收峰。因此采用多种方法的测试对比研究,可较准确的区分天然翡翠与染色翡翠,提供客观、公正的鉴定结果。

【Abstract】 A comprehensive and comparison study on natural feicui and dyed feicui have been carried out with electron probe,X-ray diffraction,Raman spectroscopy,and infrared spectroscopy,which shows the main mineral of them is jadeite.The color-causing element in the dyed feicui hasn’t been found out by the electron probe analysis.The back scattering image of the natural and dyed feicui is very different each other.According to Raman spectroscopy,the fluorescence background similar to the organic dye appears in the dyed feicui.According to IR analysis,dyed feicui shows the strong absorption peak in 2800-3100-1.Therefore,the natural and dyed feicui can be distinguished with many analysis methods,which can result in the objective and correct conclusion.
