DESIGN OF PHOSPHORS

In the choice of anions for design of phosphors, we have already established that anions can be divided into two classes, those that are optically inert and those that are optically active. The optically inert anions useful in designing phosphors are shown in the following diagram ... [Pg.458]

Now we come, in our design of phosphors, to the choice of suitable activators. Because of the limitations imposed by the ground state perturbation factor, we are limited to certain cations in specific valence states. As we have stated before, this limits us to the electron configuration d O (i So). The following diagram shows these choices ... [Pg.462]

As a matter of practical consequence, we find that concentrations of impurities much larger than about 1 ppm. have serious, deleterious effects upon any given phosphor composition. We can summarize our rules for Design of phosphors as ... [Pg.470]
