The lead mixed oxyhalides Pb₁₃O₆Cl₄Br₁₀, Pb₁₃O₆Cl₇Br₇, and Pb₁₃O₆Cl₉Br₅, with both a suitable band gap (E_g) and NLO coefficient (d_ij), satisfy all the fundamental requirements to be high‐performance mid‐IR nonlinear optical (NLO) materials. As reported by K. M. Ok and co‐workers in their Research Article (DOI: 10.1002/anie.202002291), millimeter‐sized crystals of Pb₁₃O₆Cl₄Br₁₀ and Pb₁₃O₆Cl₇Br₇, and centimeter‐sized crystals of Pb₁₃O₆Cl₉Br₅ can be grown by the flux method in an open system, which is a huge advantage compared to the growth of all the non‐oxide IR NLO crystals.

满足高性能中红外非线性光学材料所有基本要求的混合铅氧化物

铅混合的氧卤化物Pb ₁₃ O ₆ Cl ₄ Br ₁₀，Pb ₁₃ O ₆ Cl ₇ Br ₇和Pb ₁₃ O ₆ Cl ₉ Br ₅都具有合适的带隙（E _g）和NLO系数（d _ij），满足高性能中红外非线性光学（NLO）材料的所有基本要求。正如K. M. Ok及其同事在其研究文章（DOI：10.1002 / anie.202002291）中所报道的那样，Pb ₁₃ O ₆ Cl ₄ Br的毫米级晶体₁₀和Pb ₁₃ O ₆ Cl ₇ Br ₇，以及Pb ₁₃ O ₆ Cl ₉ Br _5的厘米级晶体可以通过通量法在开放系统中生长，与所有非晶体生长相比，这是一个巨大的优势。氧化IR NLO晶体。
