“…Figure 1a show the normalized emission properties of the sol-gel glass powders prepared with Al2O3/P2O5 ratio of 0.8 and a concentration of SiO2 ranging from 91.8 to 97.8mol%. The spectra exhibit broad bands around 1000 nm which are typical of Yb 3+ emission ( 2 F5/2→ 2 F7/2) bands in silica glass, the shape of which is not strongly impacted by different SiO2 contents [10][11]. However, as depicted in Figure 1b, an increase in the SiO2 content decreases the emission intensity at 1µm of the sol-gels with x=0.8 (P-rich) and 1.25 (Al-rich).…”

“…This band can be related to hydrogen-related species, [AlO4] 0 centers but also to the emission of Yb 2+ . Therefore, it is possible to think that an increase in the Al2O3 at the expense of P2O5 increases the hydrogen species, [AlO4] 0 centers and also the Yb 2+ content as suggested in [11]. At x=1, AlPO4 are expected to form at the expense of AlO4 units leading to a reduction in intensity of the band at 500nm.…”

“…Reduction in the emission intensity of Yb 3+ was observed, especially at the high P 5+ /Al 3+ molar ratio region. Xu et al reported the mechanism of the decrease in Yb 3+ absorption and emission cross sections in Al2O3-P2O5-SiO2 glass caused by P 5+ doping [11]: Yb 3+ coordinates to the P-O site in glass with molar ratio of P 5+ /Al 3+ < 1, and coordinates to the P = O site in glass with molar ratio of P 5+ /Al 3+ > 1. This change decreases the Yb 3+ asymmetry degree and thus leads to the decline in Yb 3+ absorption and emission cross sections.…”

“…This change decreases the Yb 3+ asymmetry degree and thus leads to the decline in Yb 3+ absorption and emission cross sections. However, in both studies [10][11], the authors discussed the influence of Al 3+ and P 5+ ion contents on the spectroscopic properties of Yb 3+ ions although the concentration of the SiO2 varied between ~86 and 96 mol% as the Al2O3/P2O5 ratio was changed.…”

Yb 3+ doped silica sol-gel glass powders were prepared with different concentrations of SiO2, Al2O3 and P2O5 in order to understand the impact of the glass composition on the Yb 3+ emission properties. In this paper, we clearly show that not only the Al/P ratio but also the SiO2 content have an impact on the Yb 3+ spectroscopic properties. Our results provide new insight on the real impact of the composition on the spectroscopic properties of Yb 3+ doped sol-gels: we demonstrate that an increase in the Al2O3 content at the expense of P2O5 leads to an increase in the intensity of the emission at 1000nm of the Yb 3+ ions whereas an increase in the SiO2 content decreases it. We clearly showed that the inexpensive sol-gel approach can be easily used when investigating new Yb 3+ doped silica glasses.

“…Zeng Huidan et al [13] reported that both the luminous intensity and luminous decay time of the glass appeared to have positive correlations with the amount of bridging oxygen of the glass matrix through using X-ray photoelectron spectroscopy (XPS). Hu Lili et al [14] reported the mechanism for the decrease in Yb 3+ absorption and emission intensity caused by P 5+ doping. They found that Yb 3+ coordinated to the P–O site in glass with a molar ratio of P 5+ /Al 3+ ≤ 1, and coordinated to the P=O site in glass with a molar ratio of P 5+ /Al 3+ > 1.…”

Yb3+-doped phosphate glasses containing different amounts of SiO2 were successfully synthesized by the conventional melt-quenching method. The influence mechanism of SiO2 on the structural and spectroscopic properties was investigated systematically using the micro-Raman technique. It was worth noting that the glass with 26.7 mol % SiO2 possessed the longest fluorescence lifetime (1.51 ms), the highest gain coefficient (1.10 ms·pm2), the maximum Stark splitting manifold of 2F7/2 level (781 cm−1), and the largest scalar crystal-field NJ and Yb3+ asymmetry degree. Micro-Raman spectra revealed that introducing SiO2 promoted the formation of P=O linkages, but broke the P=O linkages when the SiO2 content was greater than 26.7 mol %. Based on the previous 29Si MAS NMR experimental results, these findings further demonstrated that the formation of [SiO6] may significantly affect the formation of P=O linkages, and thus influences the spectroscopic properties of the glass. These results indicate that phosphosilicate glasses may have potential applications as a Yb3+-doped gain medium for solid-state lasers and optical fiber amplifiers.

Er‐activated fiber lasers are critical for many significant applications, including fiber communication, gas sensing, lidar and military. Although the design of suitable fiber materials has improved the performance of Er‐activated fiber lasers, extension of their operation wavebands still remains a significant challenge. Here, a compact all‐fiber laser is proposed and demonstrated, which can support lasing beyond 1630 nm, based on an Er‐activated hybridized glass fiber. The collaborative theoretical analysis and experimental characterization indicate that various distinct structure units can form in the hybridized fiber. This leads to the notable inhomogeneous spectral broadening. By using this hybridized fiber, a tunable fiber laser device is constructed and the wavelength can be rationally tuned in the range from 1609 to 1631 nm by mechanically stretching the fiber Bragg gratings (FBGs) manufactured by the point‐by‐point femtosecond laser inscription. Furthermore, a new fiber sensor system based on this seldom exploration waveband is built and efficient ethylene detection is demonstrated. The results highlight that rational hybridization mediated short‐ and medium‐structure modification strategy, demonstrated here in Er‐activated fiber laser, can be extended to other rare‐earth glass fiber systems for the exploration of fiber devices at new wavebands.
