“…Different authors tentatively assigned the different origins of this near infrared luminescence to the electronic transition derived from Bi 5+ (Fujimoto & Nakatsuka 2001;Dvoyrin, Mashinsky et al 2006;Fujimoto & Nakatsuka 2006;Ohkura, Fujimoto et al 2007), Bi 2+ Ren, Dong et al 2008), and Bi + ; Table 2): (a) transmittance spectrum shows five main absorption bands between 250 and 2000 nm, including 300 nm (A), 500 nm (B), 700 nm (C), 800 nm (D), and 1000 nm (E), and (b) luminescent spectra excited by 500, 700, 800, and 1000 nm. Dvoyrin, Mashinsky et al 2006;Arai, Suzuki et al 2007;Yang, Chen et al 2007;Zhou, Feng et al 2007;Qiu, Peng et al 2008;Ren, Dong et al 2008;Truong, Bigot et al 2008) or to that of BiO molecules (Ren, Yang et al 2006;Murata & Mouri 2007;Peng, Chen et al 2007;Peng, Wu et al 2008) dispersed in the glass host. Since most of these proposals were however analogized from only spectroscopic mesurement analysis, uncertainty remains in the present discussions.…”

“…Then the investigation of new glass compositions with Bi luminescence is also progressing vigorously in a past decade. Although the first discovered glass was a silica-based material with a SiO 2 of 97.5 mol% (Fujimoto & Nakatsuka 2001), many glass compositions were tested and shown to effectively generate Bi luminescence, such as silicate Ren, Yang et al 2006;Suzuki & Ohishi 2006;Arai, Suzuki et al 2007;Murata & Mouri 2007;Peng, Chen et al 2007;Zhou, Feng et al 2007;Peng, Wu et al 2008), germanate (Peng, Qiu et al 2004;Peng, Meng et al 2005;Peng, Wang et al 2005;Murata & Mouri 2007;Ren, Wu et al 2007;Ren, Dong et al 2007;Ren, Qiao et al 2007;Peng, Wu et al 2008;Qiu, Peng et al 2008), borate Murata & Mouri 2007;Qiu, Peng et al 2008), germanosilicate (Ren, Dong et al 2007;Ren, Dong et al 2008), and phosphate Qiu, Peng et al 2008) glasses. In this chapter, the author will introduce the basic properties of Bi doped silica glass (BiSG), such as a phase diagram and spectroscopic properties, and then mainly talk about the origine of luminescent center.…”

SiO 2 -PbO-Bi 2 O 3 glasses having the composition of 35SiO 2 -xPbO-(65-x)Bi 2 O 3 (where x = 5, 10, 15, 20, 25, 35, 45; in mol%) have been prepared using the conventional melting and annealing method. Density, molar volume and Vickers microhardness of the prepared glasses were measured. Infrared (IR) and UV-visible spectroscopic techniques were used for structural studies of these glasses. Density as well as the microhardness increase systematically and, conversely, the molar volume decreases with increasing the lead oxide content. This behavior can be explained by the correlation with the glass structure. Increasing the lead oxide content (C20 mol%) increases the network former PbO 4 groups which can play an important role in increasing the connectivity and compactness of the glass matrix via increasing the cross-linking with the other constituent silicate and bismuthate structural units. The increased compactness may explain, in turn, the increase of the density and microhardness. IR spectra reinforce the idea that bismuth participates in the glassy network predominantly as BiO 6 octahedral structural units. UV-VIS optical absorption spectra revealed UV-charge transfer absorption bands related to the contribution of Pb 2? ions in the region 350-385 nm; in addition to the extrinsic absorption of trace iron impurities in the range 220-290 nm. In the visible region, three optical bands in the ranges 415-435, 605-650 and 880-890 nm were correlated with the contribution of electronic transitions in Bi 3? ions. Calculation of the optical mobility gap and the width of the energy tail of glass from the UV-VIS absorption indicated a slight increase followed by a decrease in their values. The behavior change occurred at the glass in which PbO content is 20 mol% where lead oxide starts to participate into the glassy matrix as a network former. The combination of analytical FTIR and UVvisible spectroscopy provided a consistent picture of structure-property relations in this glass system.

“…This color center has been ascribed to Te2 -. Murata et al 9) discussed the NIR luminescence characteristics of various Bi-doped glasses based on optical basicity concept without any reducing agents, and they reported that the generation of NIR luminescence was affected strongly by optical basicity of base glass. They concluded that Λ of 0.4 was the critical point (above 0.4 no NIR luminescence was observed).…”

The effects of melting temperature and glass composition on the Near-infrared (NIR) luminescent characteristics of Tecontaining borate glasses are investigated and compared with previous works. Three absorption bands are detected at around ~370 nm, ~430 nm and ~530 nm, however, the absorption band at around ~600 nm could not be detected in all borate glasses. And no NIR luminescence was observed under the excitation of a 974 nm laser diode. The NIR luminescence was observed in Te-green and Te-purple glasses, which showed the absorption band at around ~600 nm. This absorption band was ascribed to 2 Πg → 2 Πu transition of Te2 -. Consequently, it is suggested that the origin of NIR luminescence of Te-containing green and purple glass is likely to be caused by Te2 -center. (Not to sure of the meaning of this sentence…)
