“…The relation between the glass structure and the spectroscopic properties of Yb 3+ -doped glass is revealed through the evaluation of the scalar crystal-field N J and Yb 3+ asymmetry degree. According to References [18,19,20], the scalar crystal-field N J and Yb 3+ asymmetry degree can be calculated from the Stark splitting levels, which can be derived from Lorentz fitting based on the absorption and emission spectra. As shown in Figure 3, the maximum Stark splitting manifold of the 2 F 7/2 level (781 cm −1 ) and the scalar crystal-field N J and Yb 3+ asymmetry degree are observed when the SiO 2 concentration is 26.7 mol %.…”

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.

“…The composition of glass matrix, melting temperature, and resintering temperature can be adjusted to control these properties. [ 34 ] In this work, SiO 2 ‐B 2 O 3 ‐SrO‐Na 2 O‐K 2 O components were designed as an innovative glass system to combine with above phosphors. High content SiO 2 and B 2 O 3 can form the strong glass network of [BO 4 ] and [SiO 4 ].…”

“…[ 35,37 ] When it cooled sharply into water, short chains presenting in the glass did not have enough time to connect together. [ 34 ] Thus, when glass powder was secondary resintered, [BO 4 ] and [SiO 4 ] were reconnected into a strong glass framework, meanwhile, smaller atoms like Sr 2+ (1.18 Å), Na + (1.02 Å) and K + (1.38 Å) filled the gap to maintain the stability of the glass network. [ 38 ] During this process, not only does the mixed alkali effect hinder ion exchange, but Sr 2+ also precludes the rapid flow of ions that could inhibit glass crystallization.…”

Solid‐state white lighting applications with high brightness, low power consumption and long operating life have gradually dominated the modern industrial illumination market. For applications in white light‐emitting diodes (WLEDs) and white‐lighting laser diodes (WLDs), Phosphor‐in‐Glass (PiG), owing to its facile process, high efficiency and excellent chromaticity tunability, stands out as an optimal choice among various types of color converters. Currently, research in yellow‐emitting Y3Al5O12:Ce3+ (YAG: Ce) phosphors combined with different glass system has reached a mature stage and the poor illumination is a major bottleneck. Moreover, to realize high‐quality white lighting, exploiting full‐color PiGs is of great importance for its commercialization. Herein, the multicolour PiGs their successfully obtained by deliberately matching different color‐emitting phosphors with the glass matrix. Glass composition selection rules for specific phosphors their proposed based on investigations of glass protection mechanism and the corrosion reaction between phosphors and glass matrix. In addition, an astonishing YAG: Ce PiG phenomenon (zero thermal quenching) is founded and discussed. As for practical applications, high‐quality 5‐W chip‐on‐board (COB) WLEDs their constructed by utilizing simple matches of colorful PiGs. Assembled WLDs modules also rendered a high‐efficiency and stable lighting source. These results dramatically inspire the development of high‐quality solid‐state white lighting applications.

“…Therefore, the room-temperature absorption and emission spectra were used for the analysis of Stark levels splitting. Based on our early systematic study [30,31], co-doping with Fleads to the red shift of (1 → 6,7) absorption transitions and blue shift of (5 → 2,3,4) emission transitions. Co-doping with P 5+ leads to the blue shifting of absorption transitions and emission transitions.…”

“…An effective method to decrease the RI of Yb 3+ doped core glass is incorporation of F -. Using this approach, the refractive index can be adjusted to be equal to or even lower than that of pure silica glass [15]. However, the direct incorporation of Fduring MCVD-based techniques is of limited use, since the high volatility of fluoride during preform collapsing.…”

Output power scaling of single mode large mode area (LMA) photonic crystal fiber (PCF) amplifiers urgently requires the low refractive index of Yb-doped silica glasses whilst maintaining high optical homogeneity. In this paper, we report on a promising alternative Yb/Al/F/P-co-doped silica core-glass (YAFP), which is prepared by modified sol-gel method developed by our group and highly suitable for fabricating high power LMA PCF amplifiers. By controlling the doping combinations of Al/F/P in Yb-doped silica glass,it not only ensures low refractive index (RI) but also maintains the excellent optical homogeneity and spectroscopic properties of Yb. The spectroscopic properties of Yb ions have not deteriorated by the co-doping of F and P in YAFP glass compared with that of Yb/Al co-doped silica glass. A large-size (⌀5 mm × 90 mm) YAFP silica-core glass rod with low average RI difference of 2.6 × 10 (with respect to pure silica glass), and low radial and axial RI fluctuations of ~2 × 10, was prepared. A LMA PCF with 50 µm core diameter was obtained by stack-capillary-draw techniques using YAFP core glass. Its core NA is 0.027. An average amplified power of 97 W peaking at 1030 nm and light-light efficiency of 54% are achieved from a 6.5 m long PCF in the pulse amplification laser experiment. Meanwhile, quasi-single-mode transmission is obtained with laser beam quality factor M of 1.4.
