“…The crystallographic asymmetric unit contains three unique sodium atoms, one unique samarium atom, two unique boron atoms, and six unique oxygen atoms. Each B atom is coordinated by three oxygen atoms into nearly flat BO 3 tetrahedron geometry with three B-O bond lengths of 1.352(4)-1.399(4) Å and bond angles of 116.5(3)-123.2(3) • , which is the common value in borate compounds [17,18]. All BO 3 triangles are isolated in two types of linear array, whereas Na + and Sm 3+ atoms reside among the BO 3 groups and connect them through the columbic action of Na−O and Sm−O to form the structure of Na 3 Sm(BO 3 ) 2 , as shown in Figure 2.…”

Sodium samarium borate Na 3 Sm(BO 3 ) 2 , was prepared by a flux method and structurally characterized by single-crystal structure analysis for the first time. The results show that it crystallizes in the monoclinic system P2 1 /n, with a = 6.5667(3) Å, b = 8.7675(4) Å, c = 10.1850(5), β = 90.86 • , V = 586.32(5) Å 3 and Z = 4. The structure contains NaO 7 , NaO 6 , NaO 5 , SmO 8 , and BO 3 units, which are interconnected via corner-or edge-sharing O atoms into a three-dimensional structure. The excitation spectra, emission spectra, decay time, and Commission International de l'Éclairage (CIE) chromaticity index of Na 3 Sm(BO 3 ) 2 were studied. Under near light excitation (406 nm), the powdered Na 3 Sm(BO 3 ) 2 shows the orange-red emission, which originates from the 4 G 5/2 → 6 H 9/2 and 4 G 5/2 → 6 H 7/2 transformation of Sm 3+ ion.

“…On the application side, to propose the glasses for nonlinear device applications figure of merit is a distinct criterion and is given by 60 α λ = F n 2 2 2 (8) where F is the figure of merit, α 2 is the two-photon absorption coefficient, λ is the excitation wavelength, and n 2 is the nonlinear refractive index. When the condition F < 1 is satisfied, the glasses could be used for switching applications such as passive mode locking and optical Q-switching of lasers (to produce ultrashort pulses).…”

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.

“…Due to the good monochromaticity, strong directivity, and high brightness, lasers have been used extensively in the fields of industry, communication, and information technology, through applications such as laser welding, laser etching, and free special optical. Benefiting from the frequency conversion by NLO crystals, a UV laser can be expediently and efficiently obtained [1][2][3][4]. Nowadays, some well-known borates, such as β-BaB 2 O 4 (β-BBO) [5], (LiB 3 O 5 ) (LBO) [6], CsLiB 6 O 10 (CLBO) [7] have been commercially applied.…”

A UV Nonlinear optical (NLO) crystal is one of the key devices in all-solid-state laser technology, and borate halides show outstanding potential due to their abundant structural diversity and short UV cut-off edges. In this article, the sizable UV NLO crystal of K3B6O10Br (KBOB) has been grown with lead-containing and lead-free fluxes systems using the high-temperature top-seeded solution growth (TSSG) method. Energy Dispersive X-ray Spectroscopy (EDS) and transmittance spectra illustrate the influence of Pb2+ ions on the transmittance properties and laser-induced damage threshold (LDT). The thermal property, namely, thermal expansion, thermal conductivity, and thermal diffusivity curves, were characterized. Moreover, a small variation of thermal refractive indexes was analyzed to illustrate the advantage of KBOB in the application for temperature-fluctuated specific regions.
