“…Raman band at 339 cm −1 is associated to Bi-O bond of BiO 6 octahedra for PNSiBi 05 glass. [33][34][35][36][37] The increase of Bi 3+ ions concentration may perhaps influence the shift of band position for PNSiBi 10 and PNSiBi 15 glasses. The 505-546 cm −1 band region is associated to Si-O-Si bending vibration.…”

Bismuth-oxyfluoride glasses with the chemical composition of P2O5+NaF+SiO2+Bi2O3 (PNSiBi) have been prepared by melt-quenching method and studied their structural and thermal properties through Raman, Fourier transform infrared (FTIR) and X-ray photoelectron spectroscopy (XPS) and differential thermal analysis. Moreover, elemental analysis of these glasses has been performed with energy-dispersive X-ray (EDX) spectroscopy. The glass transition and crystalline temperatures of the glasses have been estimated using differential thermal analysis (DTA). The vibrational modes of these glasses have been studied through Fourier transform infrared (FTIR) and micro-Raman analysis. Elemental compositions and binding energies of the PNSiBi glasses have been explored from XPS analysis. Binding energies of PNSiBi glasses have been obtained as 100 eV for Silicon (Si2p), 132 eV for Phosphorous (P2p), 157 and 163 eV for Bismuth (Bi 4 f) and 1069.7 eV for Sodium (Na1s). The valance states and binding energies of these elements unveiled orthophosphate (PO4)2− type structure, which forms trisodium phosphate [Na3(PO4)] with sodium and fluorides of BiF3, and (PF6)−. A 1 mol% Sm2O3 doped PNSiBi05Sm01 glass unveiled robust emission among other concentrations of Bi ions proposed that PNSiBi05 glass could be an effectual host for laser and other active photonic applications.

“…Висмутсодержащие силикатные стекла представляют интерес в связи с тем, что обладают люминесценцией в широком спектральном диапазоне от ближней УФ области до ближней ИК области, включая диапазон 1150−1800 nm, благодаря присутствию различных висмутовых активных центров (ВАЦ) [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Известны различные способы получения висмутсодержащих стеклообразных оптических материалов силикатных, алюмосиликатных, фосфатно-силикатных систем с люминесцентными свойствами.…”

“…Известно, что введение в состав силикатной матрицы фосфора приводит к увеличению степени восстановления висмута в стекле, на что указывает потемнение стекол (от коричневого до черного цвета) по мере увеличения концентрации фосфора [1]. Введение дополнительных примесей в виде P 2 O 5 или ионов F на уровне долей или нескольких массовых процентов приводит к значительному изменению спектров люминесценции по сравнению с висмутсодержащими силикатными стеклами без дополнительных легирующих добавок (ВАЦ-Si) [10, [17][18][19][20]. Особенность ВАЦ, формирующихся в фосфоросиликатных стеклах (ВАЦ-P), заключается в том, что для них характерны значительные стоксовские сдвиги большинства линий, что свидетельствуeт о существенном влиянии электрон-фононного взаимодействия по сравнению с ВАЦ-Si [10, 17,20].…”

The spectral-optical and luminescence properties of bismuth-containing composite materials based on matrices of high-silica porous glasses are investigated. Luminescence spectra, luminescence excitation spectra, infrared transmission spectra (8000–4000 cm-1) depending on the composition of different types of matrices and sintering atmosphere (nitrogen, argon) of bismuth-containing composite materials were examined. It was found that the samples of bismuth-containing composite materials are characterized by UV (λem = 350 nm), blue-green (λem = 410–550 nm) and orange-red (λem = 600–725 nm) luminescence due to the presence of various bismuth active centers. The analysis of the spectra obtained by near-infrared spectroscopy demonstrates the formation of Bi2+ dimers of bismuth and bismuth active centers associated with silicon.

“…Since Bi can provide ultra-broadband luminescence covering O-band to U-band based on appropriate hosts, Bi-doped fibers are expected to be the most potential candidate for new optical amplifiers and tunable lasers and superluminescent sources operating in near-infrared band. Currently, great efforts have been made on Bi-doped materials (i.e., aluminosilicate [1], phosphosilicate [2], and germanosilicate [3]). And various types of Bi-doped fibers have been developed and successfully used in relative amplifiers and lasers [4][5][6].…”

Bismuth (Bi)-doped silica-based glasses and fibers are attractive materials for the new optical amplifiers and tunable lasers.In this paper, Bi/Al co-doped silica glass with a relatively high Bi concentration (0.552 wt.%) were prepared by using the optimized sol-gel method. Hydrofluoric acid (HF) was used as a catalyst in the reaction, which reduced the hydroxyl to lower than 5ppm in the final glass. After the process of drying and sintering, the gel was turned into the transparent glass at low temperature (~1300 °C). The optical properties of Bi/Al co-doped silica glass were also investigated. Excited by a 980 nm laser diode (), broadband fluorescence centered at 1114 nm was obtained, which was ascribed to the Bi-Al active center (BAC-Al). The emission cross-section (𝜎 𝑒𝑚 ) was calculated to be 7.4 × 10 −21 cm 2 for BAC-Al. In addition, ultrabroadband emission ranging from 850 nm to 1700 nm was also obtained excited by the 808 nm LD, which might be ascribed to BAC-P overlapped by other BACs. After the gaussian separation of fluorescence peak, the emission crosssection for BAC-P was 13.4× 10 −21 cm 2 . Our results confirmed the potentialities of the optimized sol-gel method in Bidoped glass fabrication. The Bi/Al co-doped silica glass prepared in this work were promising to develop Bi-doped fibers and relative devices.
