Position occupied by the Activator in Impurity-activated Phosphors

Article metrics

Abstract

ALTHOUGH it is often assumed that the activator in impurity-activated phosphors is in solid solution in the matrix of the material, direct evidence of this has hitherto been lacking. Recently, G. R. Fonda1, in a general paper on fluorescence, mentions briefly that he has found an expansion of the lattice due to manganese in the case of zinc orthosilicate, but gives no experimental details.
