“…It can be seen that X 2 of BGN glass is larger than germanium [16,17], fluorophosphate [18] and ZBLAN [19] glasses but smaller than phosphate [16,17] and tellurite [17,20] glasses. It indicates that ligand asymmetry in Tm 3+ -doped BGN glass is weaker than those in phosphate and tellurium glasses.…”

“…Because of limitations of the spectrometer, only part of the spectrum of the 3 F 4  3 H 6 transition in the 1600-2000 nm can be observed. The bandwidth of the 3 H 4  3 F 4 transition is ~112 nm, which is significantly wider than the 80 nm bandwidth of Tm 3+ -doped ZBLAN but smaller than that in KBG glasses [19,20] . Intensity(a.u.…”

Abstract. Tm 3+ -doped Li 2 O-SrO-ZnO-Bi 2 O 3 (LSZB) glasses that are suitable for optical amplifier applications have been fabricated through the conventional melt-quenching method, and the spectroscopic properties of Tm 3+ in the glasses were characterized. The density, the refractive indices, the optical absorption, the Judd-Ofelt parameters Ω t , and the spontaneous transition probabilities of the glasses were measured and calculated. Using the least-squares fitting method, the Judd-Ofelt intensity parameters Ω t were found to be  2 =4.2910 -20 cm 2 ,  4 =1.1610 -20 cm 2 , and  6 =0.8410 -20 cm 2 . Intense 1.47-m fluorescence was observed in these glass systems under 785-nm excitation. The emission peak from the Tm 3+ : 3 H 4  3 F 4 transition locates around 1.47-µm with a bandwidth is ~112 nm, which is significantly wider than the bandwidth of Tm 3+ -doped ZBLAN at 80nm but smaller than that in KBG glasses. The results indicate that Tm 3+ -doped LSZB glasses is a promising host material for applications in optical amplifiers.

“…7. The value of the emission cross-section for the 3 F 4 → 3 H 6 (Tm 3+ ) transfer, corresponding to the wavelength of λ p = 1818 nm, amounts to σ em = 9.1 × 10 −21 cm 2 , which means it is significantly higher than the values of emission cross-sections for silicate glasses [26], ZBLAN [27], tellurite [30] and similar to these for germanium glasses [28,29].…”

ions. The analysis of the luminescence mechanism showed a significant influence of the glass composition (low phonon content) on the emission intensity. Optimization of the active elements content, presented in the paper, allowed to indicate that a strong emission intensity at 2 µm in the fabricated glasses was obtained for the molar composition of 1% Tm2O3 : 0.75% Ho2O3. According to the Förster-Dexter theory, the efficiency of energy transfer of the 3 F4 (Tm 3+ ) → 5 I7 (Ho 3+ ) transition was calculated. Moreover, it was found that the full width at half maximum (FWHM) of luminescence in the range of 1.6 -2.2 µm strongly depends on the Tm 3+ /Ho 3+ ratio. The optimization of Tm 3+ /Ho 3+ transfer in antimony-silicate glasses allowed to fabricate optical fibre with narrowing and red-shifting of emission at 2.1 µm.
