The fluorescent mineral on the other hand will immediately go dark. Thermoluminescence and triboluminescence are also two different things. The first is the ability of a mineral to emit visible light when heated. The second is the ability of a mineral to glow when it is crushed, scratched, or otherwise acted on by a mechanical force.

Fluorescent minerals are certain minerals that when exposed to ultraviolet radiation (light) they emit visible light. Another way to describe this process of fluorescence is when invisible short wavelength radiation is absorbed by a material and then is converted and re-emitted as a longer wavelength. noun A colorless, vitreous to resinous, often fluorescent mineral, Zn 2 SiO 4, a minor ore of zinc. chlorophane (countable and uncountable, plural chlorophanes) ( mineralogy ) A variety of fluorspar , which, when heated, gives a striking emerald-green light. 2013 , Jack DeMent, Handbook of Fluorescent Gems and Minerals - An Exposition and Catalog of the Fluorescent and Phosphorescent Gems and Minerals, Including the Use of Ultraviolet Light ...

Probably the most common fluorescent mineral, calcite is a carbonate mineral that can be found throughout the world. Calcite also comes in a variety of interesting habits, or shapes, that can resemble poker chips, dogteeth, flowers, columns, and simple blocks. Fluorescent dyes are widely used for labeling nucleic acids. Their spectra, however, can overlap with the 260 nm wavelength used to quantitate nucleic acids. When attempting to measure the UV absorbance of a fluorescently labeled nucleic acid for the purpose of quantitation, therefore, the contribution from the fluorescent dye must be corrected for.

Mar 03, 2012 · Albite is a plagioclase feldspar mineral. It is the sodium endmember of the plagioclase solid solution series. As such it represents a plagioclase with less than 10% anorthite content. The pure albite endmember has the formula NaAlSi 3 O 8. It is a tectosilicate. Its color is usually pure white, hence its name from Latin albus.

Fluorite is frequently fluorescent, i.e. it will glow under ultra-violet light. This occurs because certain electrons in the mineral absorb the energy from the ultra-violet light and jump to a higher energy state. The fluorescent light is emitted when those electrons jump down to a lower energy state and emit a light of their own.
