  • a new kbbf family nonlinear optical material with strong interlayer bonding
    Crystal Growth & Design, 2017
    Co-Authors: Yaoguo Shen, Sangen Zhao, Yi Yang, Liling Cao, Zujian Wang, Bingqing Zhao, Zhihua Sun, Zheshuai Lin, Junhua Luo
    Abstract:

    A new beryllium-free borate Rb3Ba3Li2Al4B6O20F features a layered structure analogous to that of the solely available deep-ultraviolet nonlinear optical (NLO) material KBe2BO3F2 (KBBF), and thus preserves its outstanding linear and nonlinear optical properties to a great extent. Furthermore, the interlayer bonding in Rb3Ba3Li2Al4B6O20F is significantly reinforced, with a magnitude of more than 15.6 times that of KBBF. As a result, a bulk Rb3Ba3Li2Al4B6O20F crystal is successfully grown in the preliminary experiments. The result demonstrates that the Rb3Ba3Li2Al4B6O20F crystal may have no (or only a tiny) layering growth habit, which severely hinders the practical applications of KBBF. Notably, Rb3Ba3Li2Al4B6O20F overcomes the structural Instability Problem present in the notable KBBF-family member Sr2Be2B2O7. These results make Rb3Ba3Li2Al4B6O20F a promising candidate for the next generation of deep-ultraviolet NLO materials. First-principles calculations are performed to elucidate the optical properties ...

  • designing a beryllium free deep ultraviolet nonlinear optical material without a structural Instability Problem
    Journal of the American Chemical Society, 2016
    Co-Authors: Sangen Zhao, Yaoguo Shen, Muhammad Adnan Asghar, Siyuan Zeng, Yingying Xu, Lei Kang, Xiaodong Wang, Maochun Hong
    Abstract:

    A beryllium-free deep-ultraviolet (deep-UV) nonlinear optical (NLO) material K3Ba3Li2Al4B6O20F is developed mainly by the element substitution of Be for Al and Li from Sr2Be2B2O7 that was considered as one of the most promising deep-UV NLO materials. K3Ba3Li2Al4B6O20F preserves the structural merits of Sr2Be2B2O7 and thus exhibits no layering growth tendency and possesses the optical properties required for deep-UV NLO applications, including deep-UV transparency, phase-matchability, and sufficiently large second-harmonic generation (1.5 × KH2PO4). Furthermore, it overcomes the structural Instability Problem of Sr2Be2B2O7, which is confirmed by the obtainment of large single crystals and phonon dispersion calculations. These attributes make it very attractive for next-generation deep-UV NLO materials. The substitution of Be for Al and Li in beryllium borates provides a new opportunity to design beryllium-free deep-UV NLO materials with good performance.

  • deep ultraviolet nonlinear optical material k3sr3li2al4b6o20f addressing the structural Instability Problem in kbe2bo3f2
    Inorganic Chemistry, 2017
    Co-Authors: Shilie Pan, Shiv P Halasyamani
    Abstract:

    A beryllium-free deep-ultraviolet (DUV) nonlinear-optical (NLO) material, K3Sr3Al4Li2B6O20F, has been synthesized and characterized. Unlike KBe2BO3F2 (KBBF), the reported NLO material does not require the use of toxic BeO in the synthesis, and through the judicious selection of cations, strong interlayer interactions are observed that facilitate the crystal growth. K3Sr3Al4Li2B6O20F exhibits second-harmonic generation (SHG) at both 1064 and 532 nm with efficiencies of 1.7KH2PO4 and 0.3β-BaB2O4 and has an absorption edge of 190 nm. Because of the strong interlayer interactions, we were able to grow well-faceted large crystals, 8 × 8 × 5 mm3, through a top-seeded-solution-growth technique. With these crystals, we determined a birefringence of 0.0574 at 1064 nm and a type I phase-matching SHG limit of 224 nm.
