摘要：
A series of modified porous glasses with a fixed europium content Q(Eu3+) = 30 mu mol/g and a variable titanium oxide content Q(TiO2) = 15-375 mu mol/g are synthesized. The luminescence properties of the prepared glasses are investigated as a function of the component ratio in the composition of oxide nanoparticles. The specific features of the luminescence quenching in a wet medium are analyzed. It is shown that titanium(IV) oxide substantially sensitizes the photoluminescence of Eu3+, ions and shields them aoainst the water adsorption.
