“…Three broad bands are observed at 1287 cm À1 , 1129 cm À1 and 630 cm À1 . Bands at 1287 cm À1 and 1129 cm À1 may be due to borophosphate groups [9]; however, they overlap with contributions from stretching of m(PO 2 ). A very similar spectrum is observed for P40B25Na35 (not shown).…”

“…Moreover, phosphate glasses have poor mechanical properties and this can limit their use in biomedical applications [8]. It has been demonstrated that the addition of B 2 O 3 to a phosphate network improves the chemical durability as well as thermal and mechanical stability of the pure phosphate glass [9,10]. Recently, it has also been shown that borate glasses have good bioactivity characteristics and thus a high level of potential for use in the regeneration of tissues [11].…”

“…Furthermore, the hygroscopic tendency of phosphor lowers the fluorescence lifetime of Yb 3+ ions. Some early researches [11,12] have shown that formation of P-O-B(4) bonds in borophosphate glass could greatly improve physical properties along with broad emission bandwidth. However, the photo energy of B-O bond (∼1400 cm −1 ) is larger, so that the fluorescence lifetime of borate glass is less as compared to other glass.…”

The physical properties including refractive index, Abbe number, nonlinear refractive index, microhardness and thermal expansion coefficient, and spectroscopic properties of Yb 3+ -doped fluorophosphate laser glasses were investigated. The results show that due to the addition of fluoride, mechanical and thermal properties are promoted, emission cross-section σ emi is also greatly enhanced. The largest gain coefficient σ emi · τ m (0.824 pm 2 · ms) can be obtained with the minimum pump intensity I min (1.112 kw/cm 2 ). This kind of Yb 3+ -doped fluorophosphate glass is an excellent candidate material for Yb 3+ -doped host for high-power generation.

“…It is well known that the poor water durability of phosphate glasses is attributed to the breaking of phosphate chains and their dissolution into water [7,11,14]. According to the literature [5,15] it can be seen that the P-O-Sb bonds are corrosion resistant because of their high polarizing power.…”

The influence of ZnO substitution by 0 -12 wt.% Na 2 O on the properties of ZnO-Sb 2 O 3 -P 2 O 5 -Na 2 O glasses has been investigated. The structure and properties of the glasses with the composition of (13.86-x)ZnO-57.93Sb 2 O 3 -28.21P 2 O 5−x Na 2 O (x = 0 -12 wt.%) were characterized by infrared spectra (IR), X-ray diffraction and differential thermal analysis (DTA). The results of IR indicated an increase in the intensity of symmetric vibrations of P-O-P bond, which was confirmed by the improvement of water durability with the increasing amount of Na 2 O in the range of 0 -10 wt.%. Substitution of 10 wt.% Na 2 O led to the weight loss of the glass to 5.93 mg/cm −2 after immersion in deionized water at 50°C for 24 h. The results of XRD showed that the ability of crystallization decreased, indicating the good thermal stability of the glass. The glass containing 8 wt.% Na 2 O had the best properties in every respect and might be an alternative to lead based glasses for the applications, providing further composition improvement.
