Abstract

Influence of M₂O₃ (M = Al, Ga) modifiers oxide on local structure and spectroscopic properties of lead phosphate glasses containing rare earth ions was studied. Among the rare earths, the trivalent europium and erbium ions were selected as an optically active dopants. The thermal properties were examined using DSC, whereas the X-ray diffraction analysis was used in order to verify the structure glass matrix. Luminescence of rare earth ions in lead phosphate glasses was registered in visible and NIR spectral region. The excitation and emission spectra of lead-based systems are presented and discussed in relation to the effect of modifiers oxide M₂O₃ (M = Al, Ga). Luminescence lifetimes (τm) for the ⁵D₀ state of Eu³⁺ ions and ⁴I_13/2 state of Er³⁺ ions were also evaluated.
