Formation of borophosphate glass structure within the system BaO–B2O3–P2O5

Structural and topological aspects of borophosphate glasses and their relation to physical properties

“…3,8,14,[17][18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33]65,[83][84][85][86][87] In the following, we derive analytical expressions for the amount of B and P NFUs in borophosphate glasses spanning 0 ≤ x ≤ 0.67, which is well beyond the conventional glass forming region. The structural description is simplified by separating the compositional diagram into three regions, in which different NFUs exist.…”

Low temperature InP∕Si wafer bonding using boride treated surface

“…As reported by Sedmale et al,20 with addition of P 2 O 5 , the reaction temperature for producing B 2 O 3 -P 2 O 5 glass can be decreased to as low as 300°C. Moreover, in our boride solutions, the reductive NaBH 4 can prevent the phosphor from oxidizing until the phosphor react with B 2 O 3 or SiO 2 , so the reaction temperature would be further reduced.…”

“…7 The peaks located in the range from 600 to 780 cm −1 are attributed to the vibration of boron oxide or phosphor oxide. 19,20 As shown in Fig. 6, it can be observed that the peak at 746 cm −1 is shifted to 762 cm −1 via the boride treatment.…”

Compositional effects on the thermo-optic coefficients of barium borophosphate glasses

“…γ can be determined using equation (6) and the measured properties of n, α, and dn/dT and found to range from approximately 3.7 to 2.0 as the glass changes from a phosphate-rich to a borate-rich composition (increasing B/B+P ratio). The decrease in γ accounts for the negative slope observed in Figure 8.…”
