In the past decades, glass-ceramics embedded with nanocrystals have been proved to be one kind of the most promising photonic materials for applications in optical amplifiers, tunable solid-state lasers, luminescent solar concentrators and up-conversion luminescence devices, etc. Transition metal ions and rare-earth ions singly or co-doped glass-ceramics with excellent optical properties have been developed in laboratories, and some have achieved industrialization. In this review, we highlight our recent research achievements on the design and control of the optical properties of transition metal ions and rare-earth ions doped glassceramics etc. The important properties such as multicolor luminescence, broadband near-infrared emission and optical amplification are discussed. These studies are not only helpful for understanding the optical properties of active luminescent centers doped glass-ceramics, but also valuable for the fabrication of optical devices.

“…A wide variety of traditional glass hosts containing Bi have been investigated so far, mainly silicates [1][2][3] and germanates [4][5][6] but also phosphates [7] and borates [8]. The product of the emission cross section and lifetime (σ em τ), which is inversely proportional to the laser threshold, has often been calculated and is usually found to be considerably higher than traditional laser materials such as Ti:sapphire.…”

Ultrabroad emission from a bismuth doped chalcogenide glass

Abstract:We report emission from a bismuth doped chalcogenide glass which is flattened, has a full width at half maximum (FWHM) of 600 nm, peaks at 1300 nm and covers the entire telecommunications window. At cryogenic temperatures the FWHM reaches 850 nm. The quantum efficiency and lifetime were as high as 32% and 175 µs, respectively. We also report two new bismuth emission bands at 2000 and 2600 nm. Absorption bands at 680, 850, 1020 and 1180 nm were observed. The 1180 nm absorption band was previously unobserved. We suggest that the origin of the emission in Bi:GLS is Bi 45-50 (1996). 36. J.

“…The center of the emission bands is located at 1280 nm, and the FWHM of the emissions is about 270 nm. The ultrabroadband emissions have been attributed to electronic transitions of low valence Bi or Bi clusters [30][31][32][33], but the exact origin would need further investigation. Furthermore, when excited at 808 nm, the ultrabroadband emission intensity of Bi first increases as the doping concentration of Bi 2 O 3 is increased, reaching a maximum at 3.5 mol% Bi 2 O 3 doping, and then decreases when the Bi 2 O 3 content is further increased.…”

In this work, a hybrid structure consisting of a multicomponent germanate glass microsphere containing bismuth as a gain medium is proposed and presented. The bismuth-doped germanate glass microspheres were fabricated from a glass fiber tip with no precipitation of the bismuth metal. Coupling with a fiber taper, the bismuth-doped microsphere single-mode laser was observed to lase at around 1305.8 nm using 808 nm excitation. The low threshold of absorbed pump power at 215 μW makes this microlaser appealing for various applications, including tunable lasers for a range of purposes in telecommunication, biomedical, and optical information processing.
