吸收光谱又称为晶体吸收光谱或电子光谱,它是一个较老的测试方法,过去在化学分析中用来进行比色测定。50年代末,由于仪器灵敏度的提高,吸收光谱开始大量用于透明矿物的研究。它是探讨矿物颜色形成机制(包括多色性、变色性等)的主要手段。与其它矿物物理学手段配合,通过矿物物理学的理论 Absorption spectrum, also known as the crystal absorption spectrum or the electron spectrum, is an older test method used to perform colorimetric assays in chemical analyzes. In the late 1950s, absorption spectroscopy began to be used extensively in the study of transparent minerals due to the increased sensitivity of the instrument. It is to explore the mineral color formation mechanism (including color, discoloration, etc.) the main means. In cooperation with other mineralogical methods, through the theory of mineral physics
