“…The similar type of behaviour has also been observed by other researchers [17,20]. This may be due to addition of rare earth ions having bigger radii than other constituents in the glass matrix which results in formation of nonbridging oxygens [26,27].…”

“…The values of ρ and V m were found to be in the ranges of 2.281–3.426 g cm –3 and 29.850–35.576 cm 3 mol –1 , respectively. A similar behavior was also observed with the substitution of Bi 2 O 3 for B 2 O 3 in 15Li 2 O–15K 2 O– x Bi 2 O 3 –(65 – x )B 2 O 3 :5V 2 O 5 , ZnO–Bi 2 O 3 –B 2 O 3 , and boron–silicon–bismuthate glass systems. The atomic packing density ( C g ) values of all of the glasses were calculated using the relation mentioned in ref and are presented in Table .…”

Structural and Femtosecond Third-Order Nonlinear Optical Properties of Sodium Borate Oxide Glasses: Effect of Antimony

et al. 2019

Structural and optical properties of antimony-containing sodium borate glasses were studied and their ultrafast third-order nonlinear optical (NLO) properties have been evaluated using Z-scan measurements with femtosecond (fs) pulses (∼150 fs, 80 MHz) at 750, 800, and 880 nm wavelengths. Glasses in the (mol %) 20Na 2 O−(80 − x)B 2 O 3 −xSb 2 O 3 (where x = 0, 10, 20, and 30) system have been fabricated via melt quench technique. The structural modifications were analyzed using the Raman and magic angle spinning (MAS)-nuclear magnetic resonance (NMR) ( 11 B MAS-NMR and 23 Na MAS-NMR) techniques. The optical absorption spectra revealed that the absorption edge was red-shifted, suggesting the decrease in band gap energy with increase of antimony content in the glasses. Raman scattering results revealed that the boroxol rings are depressed with the incorporation of Sb 2 O 3 for replacing B 2 O 3 . 11 B MAS-NMR results showed a progressive increase of B 4 units at the expense of B 3 units. The Raman and 11 B MAS-NMR results support the formation of Sb 5+ ions due to oxidation of Sb 3+ that played the role of charge compensation. 23 Na MAS-NMR spectra revealed a decreasing trend in the average of bond lengths of Na−O with increasing Sb 2 O 3 contents. This suggested that sodium changed its role from charge compensator to modifier cation. The antimony-containing glasses demonstrated a reverse saturable absorption in open-aperture Z-scan mode due to two-photon absorption, while closed-aperture Z-scan signatures depicted positive nonlinear refraction due to self-focusing effect. The NLO coefficients were found to increase with Sb 2 O 3 due to the increased nonbridging oxygens and also due to the hyperpolarizability of Sb 3+ and Sb 5+ ions. The observed NLO data clearly suggest that the investigated glasses are beneficial for optical limiting applications.

“…Therefore, as discussed previously, increasing the Bi 2 O 3 content increases the bond length of the BO 3 structural units, which in turn is in direct proportionality to the molar volume, and also creates more NBO. These factors, besides the weaker bond strength of Bi\O (80.3 kcal/mol) compared to the bond strength of B\O (192.7 kcal/mol), are responsible for the decrease of E g values [19,20].…”

“…But beyond 25 mol%, the increasing trend in the T g may be due to small decrease in the number of non-bridging oxygen ions and is also associated with the formation of BO 4 tetrahedra. Therefore, the non-linear variation of T g with Bi 2 O 3 content is due to the creation and variation in N 4 (BO 4 / (BO 3 + BO 4 )) units, and to some extent bridging and non-bridging oxygen ions (as seen in IR spectra) [19,26,28,23] with its structure [22]. The average electronic polarizability of ions is considered to be one of the most important properties of materials, which is closely related to their applicability in the field of optics and electronics [29].…”
