摘要
本文选取6件不同花纹不同结构的孔雀石样品,通过常规宝石学测试、显微观察、紫外—可见光光谱、红外光谱、拉曼光谱及X荧光光谱进行研究分析,可得出其在折射率、相对密度、紫外荧光等方面的特征基本相同。经红外光谱和拉曼光谱测试可见[CO3]基团引起的晶格振动及[OH]振动,具有典型的孔雀石特征峰谱图。经X荧光光谱无损测试可见明显的Cu元素峰,结合紫外—可见光光谱推测孔雀石的致色元素为Cu。
In this paper,six Malachite samples with different patterns and structures were selected and analyzed by conventional gemological tests,microscopic observation,ultraviolet visible spectrum,infrared spectrum,Raman spectrum and X-ray fluorescence spectrometer.It can be concluded that the conventional gemological characteristics of Malachite samples in refractive index,relative density and ultraviolet fluorescence are basically same.The lattice vibration and[OH]vibration caused by[CO 3]group were detected by infrared spectrum and Raman spectrum.The samples had typical characteristic peaks of malachite.The results of nondestructive testing X-ray fluorescence spectrum showed that only obvious Cu peak could be seen.Combined with UV-Vis Spectrum,it was speculated that the green color of Malachite was mainly due to Cu.
