Daily Uses of Phosphorescence

There are numerous uses for phosphorescence in daily life.  It is used in the theater to mark ledges and stairs.  When the lights go down for scene changes, the actors can still safely exit the stage.  Apart from glow in the dark toys, phosphorescence is used for more sophisticated needs.  Many watches are developed with phosphorescent materials on the hands so the user can tell the time in the dark.  The kinds of phosphorus that are commonly found in nature display this property hence the name, phosphorescence (8).
