In the 1990s a breakthrough was achieved in the development of long-lived afterglow phosphors. It was discovered that by co-doping rare earth aluminates, especially strontium, with europium and dysprosium gave phosphors with around ten times the afterglow of copper activated zinc sulfide and also with ten times the... [Pg.159]

We denote a phosphor as MaYOb Nx, where M is the cation, YOb is the anion (8issuming we have an ojgrgen-dominated phosphor and not a fluoride or sulfide), and N is the activator. It is understood that the N-cation is in sofid solution in the host-matrix, and the above formula is actually [(l-x)Ma)YOb) xNYOb]. Thus for a tin-activated strontium... [Pg.407]
