In the realm of optical and quantum computing, second-harmonic generation (SHG) serves as a valuable nonlinear optical element for both optical signal processing and quantum information processing. Herein, we report a series of innovative nonlinear optical (NLO) materials, denoted as (4-F-BTAB)ReO4, (4-Cl-BTAB)ReO4, and (4-Br-BTAB)ReO4 (BTAB = para-halobenzyltrimethylammoniun), which show illustrious high-contrast “off-on–off” SHG conversion over a broad temperature range. The precise halogen modification of cations not only achieves significant SHG signal intensity (1.08 × KDP–3.23 × KDP) but also elevates phase transition temperatures from 415.5 to 474.4 K. Notably, (4-Br-BTAB)ReO4 demonstrates a heightened SHG-active state with an increase of nearly 60 K, along with a wide band gap of 3.646 eV and enhanced piezoresponse performance of 2.25 V. This study contributes to the diversification of switchable NLO materials.

通过卤素取代调节和增强杂化芳基高铼酸铵盐的非线性光学行为
在光学和量子计算领域，二次谐波产生（SHG）是光信号处理和量子信息处理中有价值的非线性光学元件。在此，我们报告了一系列创新的非线性光学（NLO）材料，表示为（4-F-BTAB）ReO 4、（4-Cl-BTAB）ReO 4和（4-Br-BTAB）ReO 4 (BTAB =对卤代苄基三甲基铵），在较宽的温度范围内表现出出色的高对比度“关-开-关”SHG 转换。阳离子的精确卤素修饰不仅实现了显着的 SHG 信号强度 (1.08 × KDP–3.23 × KDP)，而且还将相变温度从 415.5 K 提高到 474.4 K。值得注意的是，(4-Br-BTAB)ReO 4 表现出更高的SHG-活性态增加了近 60 K，宽带隙为 3.646 eV，压电响应性能增强为 2.25 V。这项研究有助于可切换 NLO 材料的多样化。
