“…3 Peng et al found that the luminescence can extend to even 2000 nm when bismuth was doped into silicate glass. So far, bismuth NIR luminescence has been found in different glass systems such as silicate, 8,9 germanate, 10,11 phosphate, 12 chalcogenide, 13 fluoride, 14 etc., and also in different crystals such as borate, 15 chloroborate, 16 phosphate, 17 chloride 18 etc. This indicates that bismuth glasses have a great potential to be applied in fiber devices.…”

As a new member of laser glass family, bismuth‐doped glasses have received rising interests due to the application of fiber amplifiers and laser sources in the new spectral range for the next‐generation optical communication system. For practical application of the glasses, it must be considered on how to improve the luminescence efficiency. Here, we demonstrate that addition of aluminum can enhance the bismuth near‐infrared luminescence by more than 10 000 times, which is right followed by the discussion on the mechanism on why this can happen. We believe this work can be helpful for designing bismuth‐doped multiple component laser glasses with high efficiency. In addition, because of high susceptibility of bismuth to local field change, it can be used as probe ion to envision glass structures. Using bismuth as a luminescent structural probe, we can see the modifier ions of Bi+ are not completely randomly distributed inside germanate glass and they prefer the residence around tetrahedral AlO4 sites.

“…Indeed, some Bismuth-doped glasses, depending on their compositions, show remarkably wide near infrared (NIR) photoluminescence (PL) bands in the spectral range 1100–1800 nm, covering all optical telecommunication windows where the traditional rare-earths-based glasses have a rather narrow operating spectral range 1–4 . However, even though NIR emission has been observed in a variety of Bismuth-doped glasses, silica based 5 , germanate 6 , chalcogenide 7 , fluoride 8 , and chloride 9 , the exact origin of this luminescence is still unknown. Because the identification of the nature of this NIR PL is crucial for further development of efficient light sources, research efforts have been devoted to the elucidation of the nature of active NIR-luminescent centre and a number of hypotheses have been proposed to explain the origin of NIR PL in Bismuth-doped materials.…”

We report on the investigation of Bismuth-doped pure silica glass without other co-dopant by the tech- nique of magnetic circular dichroism (MCD), which allows the direct probing of the ground state of optical centres. Taking into account the results of conventional optical spectroscopy, we show that the observed MCD bands belong to the centre responsible for the red photoluminescence in this material. Measurements of the temperature and field dependences indicate that the MCD effect is caused by the even-electron system. This, however, opposes the widespread opinion that Bi2+ ions are the origin of red photoluminescence in Bismuth-doped silica glasses. On the other hand, the lasing centre responsi- ble for the near infrared photoluminescence does not exhibit any magnetic optical activity connected to its ground state. As a consequence, we conclude that the ground state of lasing centre is a magnetic singlet with the effective spin S = 0.

“…It can be used as a possible alternative to the erbium‐doped glass to prepare a superbroad fiber amplifier . In the last decade, there have been lots of reports on the observations of NIR emission in various glasses . According to numerous studies, the near‐infrared emission mechanism of bismuth‐containing materials has become clear in some peculiar systems including Bi 5 (AlCl 4 ) 3 , Bi 5 (GaCl 4 ) 3 , Bi 8 (AlCl 4 ) 2 , (K‐crypt) 2 Bi 2 , and Bi‐doped zeolites .…”

Through the order–disorder transition process of zeolites, bismuth‐doped zeolite‐derived silica glasses with broadband near‐infrared (NIR) photoluminescence have been successfully prepared by spark plasma sintering (SPS). The samples were characterized by X‐ray diffraction, UV‐vis, photoluminescence, and fluorescence lifetime. The results showed that as‐prepared samples possessed favorable broadband NIR luminescence. The NIR emission (peaked at ~1140 nm) intensity decreased with increasing the bismuth doping concentration when excited by 500 and 700 nm. The tendency was different from the emissions (peaked at ~1240 nm) excited by 800 nm. In addition, the NIR fluorescence peaks of the fixed Bi concentration sample can be observed almost around 1140 or 1240 nm when excited by different wavelengths from 500 to 950 nm. These phenomena implied that the NIR emission peaked at different wavelengths may originate from different bismuth species. Three kinds of Bi active centers Bi+, Bi0, and (Bi2)2− were proposed to contribute to the NIR emission peaks at ~1140, 1240, and 1440 nm, respectively. Interestingly, a broadband NIR emission peaked at 1207 nm with a full‐width at half maximum of 273 nm was observed when excited by 600 nm, whose intensity was stronger than that excited by 800 nm. This property might be useful for broadband fiber amplifiers and tunable lasers.
