“…Interest in glasses doped by elements with 5p and 6p electrons has noticeably increased after the discovery of infrared luminescence in Bi-doped silicate glasses [1] and the creation of fiber lasers on their base [2][3][4]. It is known now that such elements as Pb and Te can also form infrared-emitting centers when admixed to oxide glasses prepared in non-oxidizing conditions [5][6][7][8]. Such glasses are of interest as novel materials for tunable lasers and wideband amplifiers.…”

Different SnO-containing oxide glasses with various net formers (silicate, phosphate, germanate, borate, and a number of mixed compositions) were investigated for the presence of near-infrared photoluminescence. It was found that SnO-containing silicate and germanate, and also a plurality of mixed glass compositions, exhibit wideband photoluminescence peaking at 1.5-1.6 µm and with lifetimes in the order of 100 µs. These glasses are interesting as promising active materials for widely tunable fiber lasers and wideband amplifiers.

“…And then Lead (Pb) doped materials have received much attention in laser, sensor, optical communication, and so on [4,5], because of their unique electrical and optical properties. Recently, various doping materials for the special optical fiber sensors [6][7][8][9][10][11], such as Cu-doped fibers, Er-doped silica fiber, and so on are researched. However the Pb/Al codoped silica optical fiber for the Magneto-optical effect is not investigated little.…”

A Pb/Al codoped silica fibers were fabricated using atomic layer deposition (ALD) technique in combination with modified chemical vapor deposition (MCVD). PbO and Al 2 O 3 were induced into fiber core area by ALD. Faraday Effect of Pb/Al codoped silica fiber (PADF) was investigated for current sensor. Its Verdet Constant with 1 mm pitch was larger than 12 % that of single mode fiber (SMF). It is very important for fiber-optic gyroscope and fiber-optic current sensors to optimize fabrication and design optical fibers, and to obtain relatively good magneto-optic sensitivity of optical fiber. This can be improved by Pb/Al codoped materials.

“…Luminescence in NIR region with similar shape observed in germanate glasses doped with different transition metals (Sn, Sb, Pb and Bi) suggested the matrix defects induced by the dopants can be the responsible for the NIR emission [8], but this results also suggest that other transition metals can emit in NIR region. Report of luminescence in NIR region into silica glass matrix doped with transition metal is scare, but it is been observed with Pb [9] and Sn [10] doping. The optical properties of Sn doped silica glass in visible range is well studied, and normally present an oxygen deficient center with emission bands at 300 and 400nm, and excitation bands 253 and 335nm, corresponding respectively to S 1 S 0 singlet, T 1 S 0 triplet-singlet, S 0 S 1 singlet and S 0 T 1 singlet-triplet transitions [11].…”

Emission spectra of Sn, Sb, Pb and Bi doped silica glasses co-doped with Al and P prepared by modified chemical vapor-phase deposition (MCVD) using solution doping technique are presented. Bi doped silica glasses present emission/excitation (Em/Ex) bands around 470/(330, 220nm) 600/(470, 350, 270nm), 730 and 830/(820, 420, 380, 250nm), with the intensity ratio of these bands depends on the composition, indicating that different emission sources (valence states or defects) are present together. The Em/Ex of Sb doped silica glasses also depend on composition, and are similar of Bi doped silica glasses. The lifetime at 830 and 1400 in Bi or Sb doped silica glasses are similar and around 60 and 850μs, respectively. The lifetime around 600nm was 3.2 and 11μs, respectively to Bi and Sb doped silica glasses. The Sn doped silica glass present Em/Ex bands around 305/265nm, 400/(270, 340nm) and 430/280nm. The Pb doped silica glass present Em/Ex around 370/290nm and 540/320nm. No significant change in the emission bands in the visible range are observed when the Sn or Pb doped silica glass are co-doped with Al or P. The present results of Em/Ex suggest that Bi and Sb can be candidate for fiber lasing in visible range (around 600nm) using the available LD pumping (ex: 405nm). Despite Sn and Pb doping shows strong emission around 400nm, unfortunately until now there is no LD that can be used as pumping source.
