摘要：通过对白色条带的浅粉红色翡翠进行X射线荧光(XRF)光谱、拉曼光谱和紫外-可见光(UV-VIS)吸收光谱的测试分析,得出其属于硬玉型翡翠,特征拉曼位移有377,700和1039 cm-1,分别是由S-iO的不对称弯曲振动、对称弯曲振动和对称伸缩振动引起的;粉色调的产生与硬玉晶体结构中[MO6]八面体中心位置的Mn3+有关,产生的吸收峰值位于520 nm宽吸收带;浅粉红色翡翠中还可能存在着微量的致色离子Fe3+,Mn2+和Cr3+,并对它们产生的吸收峰也进行了指派。
X-ray fluorescence （XRF） spectrum, Raman spectrum and ultraviolet-visible （UV-VIS） absorption spectrum are used for analyzing the samples of light pink-red jadeites with white banded struture. It shows that this type of jadeite is assigned to jadeite jade, and it also has diagnostic Raman shifts located at 377, 700 and 1039 cm^-1 , which are respectively attributed to unsymmetrical bending, symmetrical bending and symmetrical strecthing of Si-O band; Light pink-red color of jadeite is attributed to Mn^3＋ located at the center of [-MO6] octahedral in crystal structure, and d-d transitions of Mn^3＋ bring one wide absorption band centered at 520 nm. Additionally, there are many types of minor color-causing ions being in light pink-red jadeite, such as Fe^3＋ , Mn^2＋ and Cr^3＋, and also their absorption bands are assigned.
