Abstract
The phenomenon of luminescence was first studied by Stokes in about 1852. Stokes noticed that when fluorspar was placed in the sun it seemed to glow. The orange jackets of highway workers that appear very bright even on cloudy days, road signs that “glow in the night,” and the afterglow when a television set is turned off are modem examples of this phenomenon. Luminescence is a general term to describe systems that can be made to glow. Such systems can be classified according to the glow-producing mechanism. The two major divisions of present-day analytical importance are fluorescence and phosphorescence.
