Spectral properties and dynamics of luminescent states of Pr3+ and Tm3+ in lead borate glasses modified by PbF2

Role of PbO substitution by PbF2 on structural behavior and luminescence of rare earth-doped lead borate glass

“…Luminescence spectra recorded for the oxide and oxyfluoride lead borate glasses containing Pr 3+ [7][8][9], Eu 3+ [10][11][12] and Er 3+ [13][14][15] ions have been investigated in detail. Fig.…”

“…Luminescence spectra recorded for oxide and oxyfluoride lead borate glasses doped with rare earth ions. [9]. The luminescence intensity variations for Eu 3+ [12] and Er 3+ [15] ions in lead borate glasses have been analyzed in our previous works.…”

Luminescence spectroscopy of rare earth-doped oxychloride lead borate glasses

“…In this system, lead oxide plays the role of glass former or glass modifier, influencing strongly the structure and optical properties of rare earth ions, which depends on PbO content in the borate glass matrix. Moreover, the introduction of PbF 2 to lead borate glass [6,7] as well as other glass matrices [8][9][10] significantly enhanced luminescence of Ln 3 + ions. The experimental results obtained for Ln-doped glasses modified by PbF 2 are well documented.…”

IR, density and DTA studies the effect of replacing Pb3O4 by CuO in pseudo-binary Li2B4O7–Pb3O4 glass system

“…Lead borate glasses are of technological interest owing to their properties such as their low melting temperatures, wide glass formation regions, good radiation shielding properties, and its technological and industrial interests for their use in enamels, photonics, and optoelectronic applications [1][2][3][4]. IR spectroscopic work has been carried out in lead borate glasses [5], in which the low frequency IR peaks involving PbO vibrations were observed, indicting the appearance of new bands characteristic of covalent PbO bonds with the increased content of PbO.…”
