Introduction
Fluorescent gems, also known as fluorescent minerals, are a fascinating and beautiful group of gemstones that emit light when exposed to ultraviolet (UV) radiation. This phenomenon, known as fluorescence, occurs when certain minerals absorb UV radiation and then re-emit it as visible light.
Gems That Fluoresce
- Alexandrite
Alexandrite is a rare and valuable gemstone that is known for its color-changing properties. It appears green in daylight but changes to red under incandescent light. This unique trait is caused by the presence of chromium impurities, which absorb specific wavelengths of light. Alexandrite also exhibits strong fluorescence under UV light, emitting a bright red glow.
- Fluorite
Fluorite is a common mineral that is found in a wide range of colors, including purple, green, blue, and yellow. It is also an excellent fluorescent mineral, emitting a bright blue or green glow under UV light. This fluorescence is caused by the presence of calcium and fluorine ions within the crystal structure.
- Scheelite
Scheelite is a calcium tungstate mineral that is typically found in white or yellow. It is also a strong fluorescent mineral, emitting a bright blue or white glow under UV light. This fluorescence is caused by the presence of tungsten ions within the crystal structure.
- Smithsonite
Smithsonite is a zinc carbonate mineral that is typically found in green or blue. It is also a fluorescent mineral, emitting a bright green or blue glow under UV light. This fluorescence is caused by the presence of zinc ions within the crystal structure.
- Willemite
Willemite is a zinc silicate mineral that is typically found in white or green. It is also a fluorescent mineral, emitting a bright green glow under UV light. This fluorescence is caused by the presence of manganese ions within the crystal structure.
Applications of Fluorescent Gems
Fluorescent gems have a wide range of applications, including:
Jewelry: Fluorescent gems are often used in jewelry, as their unique glow can add an extra touch of beauty and interest.
Lighting: Fluorescent gems can be used in lighting, as they can emit light when exposed to UV radiation. This makes them ideal for use in night lights, decorative lighting, and other applications.
Medical: Fluorescent gems can be used in medical applications, as they can help to diagnose and treat certain conditions.
Fluorescence vs. Phosphorescence
Fluorescence and phosphorescence are two similar phenomena that are often confused. However, there is a key difference between the two. Fluorescence is the emission of light by a substance that has absorbed UV radiation. Phosphorescence is the emission of light by a substance that has absorbed UV radiation and then continues to emit light for a period of time after the UV radiation has been removed.
Table: Overview of Fluorescent Gems
| Gemstone | Color | Fluorescence |
|---|---|---|
| Alexandrite | Green/Red | Red |
| Fluorite | Purple/Green/Blue/Yellow | Blue/Green |
| Scheelite | White/Yellow | Blue/White |
| Smithsonite | Green/Blue | Green/Blue |
| Willemite | White/Green | Green |
