矿物受激后将以光子形式释放出能量，所放出的光子可以是Ｘ射线、紫外线、可见光、红外线等，这些都是广义的荧光，可见光仅是其中极小的一部分。荧光的各种性质如波长，强度，温度特性，余辉时间都可能反映矿物种类、杂质、晶体缺陷、有序度、结构、价态、原子团等信息，...
When excited, the minerals will release their energy in the form of photons. The released photons may be X-rays, ultraviolet rays, visible rays, infrared rays and the like. These are the generalized fluorescences, of which the visible light is only a very small part. Fluorescence properties such as wavelength, intensity, temperature characteristics, afterglow time may reflect the mineral species, impurities, crystal defects, degree of order, structure, valence, atomic groups and other information, ...
