Fluorescence and phosphorescence are related but distinct properties of minerals. Fluorescence occurs when a mineral absorbs energy and emits light almost instantly, typically within nanoseconds, while phosphorescence involves a delayed emission of light that can persist for seconds to hours after the excitation source is removed. Both phenomena result from the excitation of electrons, but the mechanisms and durations of light emission differ significantly. Thus, while they share similarities, they are not the same mineral property.
The ability of a mineral or substance to glow during and after exposure to ultraviolet light is called fluorescence. If it continues to glow after the ultraviolet light has been turned off the effect is called phosphorescence.
Gypsum itself is not phosphorescent; it is a mineral composed of calcium sulfate dihydrate. Phosphorescence refers to the property of certain materials to absorb light and then re-emit it over time, which is not a characteristic of gypsum. However, some gypsum crystals may exhibit fluorescence under specific lighting conditions, but this is different from phosphorescence.
Fluorescence is not a mineral at all.
Fluorescence was first discovered in 1852 by British scientist Sir George Stokes. He observed that certain minerals, when exposed to ultraviolet light, emitted visible light of a different color. This phenomenon became known as fluorescence in honor of the mineral fluorite, which exhibited this property.
Yes, some types of mica can exhibit fluorescence under ultraviolet light. The fluorescence is often caused by impurities or trace elements in the mica mineral structure, resulting in different colors such as white, yellow, or green fluorescence.

Fluorescence is a property not a mineral.
Yes
The two main types of mineral luminescence are photoluminescence and cathodoluminescence. The excitation sources are ultraviolet radiation and electrons, respectively. Other types are ionoluminescence, chemiluminescence and others. - See the related link below.
The fluorescence in a mineral is where it will shine or reflect under a ultraviolet light.
The fluorescence of a mineral refers to its ability to emit visible light when exposed to ultraviolet light. This property can provide information about the mineral's composition, impurities, or crystal structure. Fluorescence is commonly used in mineral identification and research.
Fluorite is a fluorescent mineral.

Phosphorescence can be useful in mining eucryptite because it can help identify the presence of this mineral in the ore. Eucryptite typically exhibits phosphorescence under ultraviolet light, making it easier to distinguish from other minerals. This property can aid miners in locating and extracting eucryptite from the surrounding material.
The fluorescence is experimentally identified.You need an ultraviolet lamp to irradiate the mineral sample.

Fluorescence is a special property that only applies to a few minerals. It refers to the ability of a mineral to emit visible light when exposed to ultraviolet light.
