Energy Transfer

Abstract

In Chapter 2, the luminescent center was brought into the excited state, whereas in Chapters 3 and 4 the return to the ground state was considered, radiatively and nonradiatively, respectively. In this chapter another possibility to return to the ground state is considered, viz. by transfer of the excitation energy from the excited centre (S*) to another centre (A): {\$}{\$}S^* + A {\backslash}to {\backslash},S + A^*{\$}{\$}(Figs 1.3 and 1.4).
