摘要
翡翠在紫外光下的荧光现象，主要与翡翠矿物中Cr及Fe的含量有关，荧光强度的倒数与矿物中的比值成正变关系。在荧光观察中要注意矿物裂隙及微量矿物杂质“绵”的影响，外来物质蜡、油、胶粘剂可导致翡翠异常荧光，并据此作为翡翠经受“处理”的判定依据之一。
The luminescence of feicui under ultraviolet ray is mainly related to the content of Cr and Fe in feicui mineral, the reciprocal of fluorescence intensity in positive correlation to the ratio (Cr+Fe) / (Al +Cr+Fe ). In fluorescence observation, we must pay attention to the effects of mineral fissure and trace mineral impurity. Foreign wax, oil and colloid binder can cause feicui's anomalous fluorescence. It is one of the evidences to discriminate whether the feicui processed or not
