摘要: The non-resonant transfer of optical excitation between inorganic ions in solids is discussed and reviewed. When there no pairwise resonance electronic transitions the donor acceptor, higher-order phonon-assisted many-body processes become important. theories are briefly described relative importance two mechanisms discussed. Attention given to dependence probability on temperature, energy gap concentration species involved process, particularly case they trivalent lanthanide ions. Experimental examples concerning Tb3+→Eu3+ Tb1−xEuxP5O14 Cs2NaTb1−xEuxCl6 reported, order show how theoretical concepts can be applied real cases.
