Many types of calcite and amber will fluoresce under shortwave UV, longwave UV and visible light. Rubies, emeralds, and diamonds exhibit red fluorescence under long-wave UV, blue and sometimes green light; diamonds also emit light under X-ray radiation. Fluorescence in minerals is caused by a wide range of activators. In some cases, the ...
Blacklight fluorescent tubes. The violet glow of a blacklight is not the UV light itself, but visible light that escapes being filtered out by the filter material in the glass envelope. A blacklight, also called a UV-A light, Wood's lamp, or ultraviolet light, is a lamp that emits long-wave ultraviolet light and very little visible light.
A sample of hyalite Fluorescent hyalite under an ultraviolet blacklight. Hyalite is a transparent form of opal with a glassy lustre. It may exhibit an internal play of colors if natural inclusions are present. It is also called Muller's glass, water opal, and jalite. Müller's glass is named after its discoverer, Franz-Joseph Müller von ...
It is highly fluorescent (green) under shortwave ultraviolet light. It occurs in a variety of colors in daylight, in fibrous masses and apple-green gemmy masses. Troostite is a variant in which part of the zinc is partly replaced by manganese, it occurs in solid brown masses. It was discovered in 1829 in the Belgian Vieille-Montagne mine.
Collection of various fluorescent minerals under UV-A, UV-B and UV-C light. Cool looking picture, but also encyclopedic. I had no idea about the range of fluoresing rocks. It appears in Fluorescence and Ultraviolet. It was created by User:Hgrobe. Nominate and support. - Ravedave (help name my baby) 04:58, 3 October 2006 (UTC) support.
Autunite (hydrated calcium uranyl phosphate), with formula Ca(UO 2) 2 (PO 4) 2 ·10–12H 2 O, is a yellow-greenish fluorescent phosphate mineral with a hardness of 2– 2 + 1 ⁄ 2. [4] [5] Autunite crystallizes in the orthorhombic system and often occurs as tabular square crystals, commonly in small crusts or in fan-like masses.
