【摘要】 贵翠的ESR研究表明,其谱是由白色石英、绿色地开石和有机质中的顺磁中心共同作出贡献的结果。这些顺磁中心是:石英的辐射中心（g≌2.01）;地开石晶格中的Fe₁³⁺（g_⊥=4.03,g_w=4.26）,Fe₂³⁺(g_⊥=3.41,g_?=3.18)和VO²⁺(g_⊥=1.981,g_?=1.938,A_⊥=64.3高斯,A_w=185.4高斯)以及吸附有机质的自由基等。再次证明,贵翠的蓝绿色是地开石中Cr³⁺引起的。贵翠被加工成艺术品之后应避强光、高温、射线。更多还原

【Abstract】 "Guizhou jadeite", a gem stone, has been investigated by ESR. It is a superposed spectrum of white quartz,green dickite and organic substance. The paramagnetic centers in "Guizhou jadeite" are radiation center in quartz （g 2.01）;Fe₁³⁺（g_⊥=4.03,g〃=4.26）,Fe₂³⁺（g_⊥=3.41,g〃=3.18） and VO²⁺（g_⊥=1.981,g〃=1.938, A_⊥=64.3G, A〃=185.4G） in crystal structure of dickite; organic radical and so on. It is shown again that the blue-green color of "Guizhou jadeite is caused by Cr³⁺ in dickite.更多还原
