Photoluminescence and optical transition properties of Sm3+ activated lead-borate glasses

Computational analysis, Urbach energy and Judd–Ofelt parameter of warm Sm3+complexes having applications in photovoltaic and display devices

“…The outcomes of all parameters of complexes ( C1–C6 ) are comparable with erbium and samarium-doped glass value. 87–89 The lasing properties of the synthesised complexes were compared with previously reported similar Sm 3+ complexes (Table 8). In the C1–C6 complexes, gain bandwidth values are higher than the literature value, suggesting that the materiality of these complexes is in the broad band range optical devices.…”

“…The optical parameters gain bandwidth (s(l p )*Dl eff × 10 −28 cm 3 ) and optical gain (s(l p )*s R × 10 −25 cm 2 s) were also estimated using the SEC. 87,88 Laser device amplication is dependent on the optical gain (s(l p )*s R × 10 −25 cm 2 s) and the values are listed in Table 8. The outcomes of all parameters of complexes (C1-C6) are comparable with erbium and samarium-doped glass value.…”

Structural, photoluminescence, and optical characteristics of a Sm3+‐doped lead borate–strontium–tungsten glass system: Evaluation of Judd–Ofelt intensity parameters and radiative properties

“…Analyzing the IR spectra, it was observed that, as the samarium content was increased, the bands became narrower, sharper, and the intensities could be clearly seen to increase. The peaks in the band region 400–500 cm −1 resulting from the Pb + and Sm + metal ions vibrations in the glass matrix [25, 26] were also enhanced. New small peaks at 2850.4 and 2921 cm −1 were visible, but these were assigned to hydrogen bonding due to the lead oxide [25, 27].…”

“…When incorporated into a suitable host glass network, samarium provides good luminescence in the visible region [7, 9]. The emission of the Sm 3+ ions is not influenced by the high phonon energy, which is why borate glass are widely used in doping with samarium [10, 12, 13, 23–30]. Samarium is considered a promising material for use in optical fibres, specifically in optical amplifiers [22].…”
