A two-dimensional (2D) nonlinear-optical (NLO) material could generate a breakthrough in the development of a nanoscale laser, especially in the range of high-energy and short-wavelength deep ultraviolet (DUV; <200 nm). KBeBOF (KBBF) is the only bulk crystal actually used in the DUV region. In this letter, we designed the new 2D KBBF family monolayer AlLiBOF (2D-ALBF), which was predicted to have a broad DUV-vis transparent range and an enhanced NLO effect that doubles the frequency. 2D-ALBF keeps the infinite planar [BeBOF] structure in KBBF but does not contain the toxic beryllium element.
二维（2D）非线性光学（NLO）材料可能会在纳米尺度激光的发展中取得突破，特别是在高能和短波长深紫外（DUV；<200nm）范围内。KBeBOF（KBBF）是唯一实际应用于 DUV 区域的块状晶体。在这封信件中，我们设计了新的二维 KBBF 族单层 AlLiBOF（2D-ALBF），它预计具有更宽的 DUV-可见透明范围和增强的 NLO 效应，可将频率提高一倍。2D-ALBF 保留了 KBBF 中无限平面的[BeBOF]结构，但不包含有毒的铍元素。
