Abstract

We fulfilled systematic investigations of energy transfer(ET) processes for more than 60 donor(d)-acceptor(a) systems of RE³⁺ in wide line of phosphate, silicate, borate, germanate, and tellurite glass hosts, also as in crystals of pentaphosphates, tetraphosphates, double potassium molibdates, and so on, with using the arsenal of modern precise experimental methods, in particular, the selective laser excitation method, or the method of luminescence decay kinetic in the intensity range of 4-5 orders of value. New significant results were obtained which allowed us to form the clear viewpoint on the regularities and mechanisms of different ET processes, the dependences of their constants from composition and micriscopic structure of host, the activator concentrations, the temperature, the energy mis-match, and the other factors, also as on the principal changes of ET regularities when crossing from crystalline to amorphous state.
