Fluorescence in geology is a term used to refer to a minerals ability to absorb certain wavelengths of ultraviolet light and emit it at a different wavelength. While some minerals may look spectacular and colourful in natural light, others may look dull, bland, boring and uninspiring. However, some minerals have the ability to fluoresce when exposed to certain wavelengths of ultraviolet lighting. When hit by a uv light source, such as a shortwave UV lamp, fluorescent minerals absorb the light and emit it at a different wavelength. This causes them to appear in a drastically different and often extremely luminous and vibrant colours than it would appear in sunlight. In this section, you will be able to find many mineral specimens which have fluorescent capabilities. All the specimens featured in this section were photgraphed using a standard digital camera whilst the samples were exposed under shortwave (254 nm) uv lighting emitted from a mains power supplied 8 watt uv lamp.
