Storage of light sum by FKP-0.3k and ZnS(Ag) phosphors during excitation by atomic hydrogen

An analysis is made of the mechanism by which the light sum is stored during radical-recombination luminescence. There may be two processes leading to storage of the light sum (ΣRRL): one due to diffusion of holes and electrons from the crystal into the interior, and one due to photoexcitation. The measured dependences of ΣRRL on the amount of phosphor in the sample for the FKP-0.3k and on the thickness of a ZnS(Ag) crystal furnish evidence that photoexcitation is the governing process. The diffusion process, on the other hand, aids deexcitation, because the hole mobility is much less than the electron mobility.
