SOME ASPECTS OF THE DECAY OF PHOSPHORESCENCE

Abstract

IN ORDER TO OBTAIN AN EFFICIENT MEMORY DEVICE FOR USE WITH THE SPOTTING RI LE OF RECOILLESS WEAPON SYSTEMS, A STUDY WAS MADE TO DETERMINE THE MECHANISMS AND PARAMETERS AFFECTING THE PERSISTENCE OF PHOSPHORESCENCE AND METHODS OF MAXIMIZING THE PERSISTENCE FOR A GIVEN ENERGY OF EXCITATION. An expression is derived for the maximum persistence obtainable for a given energy input in terms of the decay constant of the phosphor and it is shown that the problem of maximizing the persistence is related to the problem of minimizing the energy needed for any desired persistence. The maximum useful ra ge for the memory device applied to the spotting weapon of a recoilless weapon system is discussed. (Author)
