Ultraviolet Lights for Mineral Fluorescence

  • Manuel Robbins

Abstract

Alchemists stumbled upon minerals or mineral preparations which, when held for a time in the sun and then quickly taken indoors, would continue to glow. The long wave ultraviolet and the visible violet produced by the sun were the sources of excitation of this phosphorescent response. A few minerals fluoresce with such intensity that the effect is noticeable in sunlight. Thus, some willemites owe their intense green color in daylight to the fluorescence produced by solar ultraviolet; some fluorites, their blue; and some rubies, their red in part to this effect.
