Спектрально-люминесцентные свойства и перенос энергии в фосфатных стеклах с высокой концентрацией ионов WO²⁺ и Tb³⁺

Abstract

The luminescence and kinetic characteristics of activated Tb³⁺ tungsten diophosphate glasses have been studied. In has been found the presence of electronic excitation energy transfer in a system WO²⁺ →Tb³⁺, which provides a high level of luminescence yield. Dissipation of Tb³⁺ ions excitation in turn occurs by resonance and diffusion mechanisms. Micro- and macroparameters of Tb — Tm excitation have been determined.
