Abstract

Nonradiative energy transfer between donor and acceptor ions in solids takes place by various processes, i.e. dipole-dipole, exchange, etc. Also, before transfer, migration of excitation energy among donors may occur and may influence the time evolution of the donor and acceptor luminescence. It is well known that, regardless of the process present, the decay pattern of the donor ions is affected by the presence of the acceptor ions.
