Unlike fluorescence, which stops almost immediately when ultraviolet light is switched off, phosphorescence creates a temporary afterglow that may remain visible for a fraction of a second or, in some mineral species, for several minutes.\u003c\/p\u003e\n\u003cp data-start=\"792\" data-end=\"1228\"\u003ePhosphorescence occurs when energy absorbed from ultraviolet light is released more slowly by the mineral. The duration and intensity of the afterglow depend on the mineral's crystal structure, chemical composition and the conditions under which it is examined. This fascinating optical behaviour makes phosphorescent minerals particularly popular with collectors, educators and anyone interested in the science of mineral luminescence.\u003c\/p\u003e\n\u003cp data-start=\"1230\" data-end=\"1550\"\u003ePhosphorescent minerals may first fluoresce under \u003cstrong data-start=\"1280\" data-end=\"1298\"\u003eLong Wave (LW)\u003c\/strong\u003e, \u003cstrong data-start=\"1300\" data-end=\"1320\"\u003eMedium Wave (MW)\u003c\/strong\u003e or \u003cstrong data-start=\"1324\" data-end=\"1343\"\u003eShort Wave (SW)\u003c\/strong\u003e ultraviolet light before producing an afterglow once the ultraviolet source is removed.
