宝石的颜色是决定其价格的重要条件,天然宝石中颜色好的极少,尤其是水晶,贮量最多的是无色的,而彩晶是非常稀罕的。因此,人工改色和改色机理的研究倍受重视。一般认为,宝石的鲜艳颜色与其体内存在的微量色素元素有关。本工作是用中子活化分析法测定无色的和浅黄、浅烟、浅粉、浅紫等彩晶中的微量元素,了解它们与颜色的关系,为人工改色提供数据。取50—150mg样品,根据待测元素的核特性,分为短照、中照、长照三组,分别
The color of the gem is an important condition for the price of the gem. There are very few colors in natural gemstones, especially the crystal. The most abundant color is colorless, while the color crystal is very rare. Therefore, the research on the mechanism of color change and color change has drawn much attention. It is generally believed that the vivid color of gems is related to the trace pigment elements present in the body. This work is the determination of trace elements in colorless and pale yellow, light smoke, light pink, light purple and other color crystals by neutron activation analysis to understand their relationship with the color, to provide data for the artificial color change. Take 50-150mg samples, according to the nuclear characteristics of the elements to be tested, divided into short, middle and long according to the three groups, respectively
