阴极显微发光下识别翡翠

IDENTIFICATION OF JADEITE JADE WITH CATHODE LUMINESCENCE MICROSCOPE

在阴极发光下翡翠的主要矿物成分硬玉通常发暗—中亮绿—黄绿色光 ;当硬玉成分较纯时发亮紫红色光 ;当硬玉中不含铁而含钙和锰时往往发中—亮紫蓝色光和白色光。在阴极显微镜下翡翠的结构清楚可鉴 ;A、 B、 C货各有其明显的区别特征 ;依据 CL图像能较好地区分翡翠和其它相似玉或仿制品。

The common colour of jadeite jade which consists of jadeite, is green to yellow green with dark to middle bright under cathode luminescence. Jadeite with pure composition will display bright purple red, while it contains calcium and manganese but nonferrous, the colour is purple blue and white with middle bright to bright. The features of jadeite jade can be discriminated clearly with cathode luminescence. A, B and C jadeite jades can be identified just because of their own characteristic colours. Jadeite jade differs from other gem and jade by luminescence characteristic and they can be distinguished most easily with cathode luminescence.
