摘要

成功设计并合成了两种新型稀土硼酸盐 NLO 晶体 K6NaSrY2B15O30 和 Rb7BaLu2B15O30，它们具有 NLO 活性 [B5O10] 基团和 [Y/LuO6] 多面体。它们的紫外吸收截止边明显短于 200 纳米，宽带隙超过 6.2 eV，并且具有与 KDP 相当的强二次谐波发生强度。这些发现表明，这两种化合物在短波紫外窗口中都是很有前途的 NLO 候选物质。

Designing rare earth borates as UV nonlinear optical crystals exhibiting strong second-harmonic generation responses.

Two new rare earth borate NLO crystals, K₆NaSrY₂B₁₅O₃₀ and Rb₇BaLu₂B₁₅O₃₀, were successfully designed and synthesized, which feature NLO-active [B₅O₁₀] groups and [Y/LuO₆] polyhedra. They exhibit notably short UV absorption cutoff edges below 200 nm, wide band gaps exceeding 6.2 eV, and strong second-harmonic generation intensities that are comparable to KDP. These findings suggest that both compounds are promising NLO candidates in the short-wave UV window.
