Abstract

This paper reports the time-resolved luminescence and excitation-emission matrix (EEM) measurements of three different boro-silicate host glasses doped with Eu³⁺. The effect of zinc and tellurium oxide addition on the photoluminescence (PL) and time-resolved emission spectra (TRES) of the glasses was also studied. At 392 nm of excitation wavelength, a bright red electric dipole (ED) transition ⁵D₀ → ⁷F₂ (615 nm) and a weak orange magnetic dipole (MD) transition ⁵D₀ → ⁷F₁ (590 nm) were observed. The asymmetric ratio (ED/MD) values were increased in the order Eu < Eu-Zn < Eu-Te. The decay associated spectra (DAS) showed a bright red emission transition (⁵D₀ → ⁷F₂) at 612 nm for all glasses. The time-resolved analysis revealed that, because of the glass network randomness, the luminescence emissions did not present the same lifetime or wavelength for the same transition bands, attributed to different environments (or interactions) experienced by Eu³⁺ ions in the glass network.
