WebA phosphor is a material that luminesces when exposed to a stimulating radiation. Often there is a matrix, for example ZnS and an activator. Examples of activators are silver in ZnS:Ag or copper in ZnS:Cu. The activator concentration in the matrix can be less than 0.01% in some systems up to well over several percent in others.
