Colouration Mechanism and VIS, IR Spectra of Emerald from Malipo, Yunnan Province

摘要: 以云南祖母绿为研究对象,采用LRM,IR,UV-VIS等现代测试分析方法,重点对云南麻栗坡祖母绿的可见、红外吸收光谱及呈色机理进行研究。揭示该类型祖母绿中水分子的存在形式及振动类型,并进一步探讨其呈色机理。

Abstract: UV-VIS, IR spectra and colouration mechanism of the emerald from Malipo, Yunnan Province, are studied. The LRM, IR and UV-VIS analytical testing techniques are employed in the research. The vibration types and existence format of water in the emerald are revealed. Further, the colouration mechanism of the emerald is discussed.
