Broadband near-infrared luminescence in bismuth borate glasses

Spectroscopic investigations on alkali earth bismuth borate glasses doped with CuO

“…The intensity of the peak decreases with increasing copper concentration and also by the integration of CaO with BaO. QIU et al [11] also observed similar visible luminescence results for 75B 2 O 3 -25Bi 2 O 3 glass samples.…”

“…Various single crystal borates including LaGeBO 5 , BaB 2 O 4 , BiB 3 O 6 , and BaBiBO 4 have been investigated and reported to possess promising physical properties [9,10]. Qui et al [11] observed that 75B 2 O 3 -25 Bi 2 O 3 glass is a good candidate for broad band optical amplification and laser material covering the wavelength from 1100 to 1300 nm.…”

The broadband NIR emission properties of Bi doped La2O3–Al2O3–SiO2 glass

“…Meng et al [4] attributed the long lifetime NIR emission to the radiative transition of 3 P 1 -3 P 0 from Bi þ ion. Qiu, Zhou and Ren supported Meng's opinion [14,15,37]. Peng et al attributed NIR emission to Bi 0 in bismuthate glass [25] and Bi-doped Ba 2 P 2 O 7 crystals [28].…”

“…The first bismuth fiber laser was constructed with Bi-doped silica-based optical fibers using MCVD technology by Dianov in 2005 [11,12], and its slope efficiency achieved $ 30%. Broadband NIR emission has been observed from different bismuth doped silicate [1][2][3]9,13,[15][16][17]23,[30][31][32], phosphate [4,5,42], germanate [6][7][8]33,34,38,39], bisumthate [25], borate [14], and chalcogenide [10,35] glasses, as well as some crystals [28,29]. The optical properties such as absorption spectra, emission spectra and lifetime of Bi ions are noticeably affected by glass hosts as well as the composition of glass host.…”

Specific features of fluorescence kinetics of Pr+3 doped BiB3O6 glasses

“…Studies of the BiB 3 O 6 (BiBO) glasses are of an essential interest due to promising nonlinear optical and optoelectronic optical fibers features [1][2][3]. Following the Raman data, the principal structural fragments of such glasses are BO 3 and BO 4 sub-units [4], which possess relatively high phonon frequencies (up to 1600 cm À1 , giving substantial contribution to electron-phonon anharmonic interactions).…”
