Abstract

Solvent evaporation was employed to grow an optical bulk single crystal of Glycine Methyl Ester Hydrochloride (GMEHCl), which was first reported in the literature. It crystallizes with the space group P2₁/c in a monoclinic system and was confirmed by single crystal X-ray diffraction. FT-IR analysis verified the various functional groups. Optical characteristics were evaluated using UV-Vis-NIR analysis, it was observed with an optical bandgap of 5.10 eV, and the cut-off wavelength was 230 nm. Photoluminescence analysis of the material reveals great structural perfection, supporting the suitability of the produced crystal for the emission of blue fluorescence. Thermal assessment disclosed that the compound was steady until 176 °C. Third-order nonlinear optical properties of glycine methyl ester hydrochloride were determined using the Z-scan approach. Third-order nonlinear properties β, n₂, and \({\upchi }^{3}\) of GMEHCl were determined to be 1.37 × 10⁻⁴ cm/W, 3.37 × 10⁻⁹ cm²/W, and 3.56 × 10⁻⁶ esu, respectively. This result indicates that the crystal may have uses in various NLO and photonic device configurations.

用于光电应用的甘氨酸甲酯盐酸盐单晶的合成、生长、光致发光、热和三阶非线性光学性质

摘要

采用溶剂蒸发法生长甘氨酸甲酯盐酸盐（GMEHCl）的光学块状单晶，这是文献中首次报道的。它以单斜晶系空间群P2 ₁ /c结晶，并通过单晶X射线衍射证实。 FT-IR 分析验证了各种官能团。使用UV-Vis-NIR分析评估光学特性，以5.10eV的光学带隙进行观察，截止波长为230nm。该材料的光致发光分析显示出非常完美的结构，支持所生产的晶体适合发射蓝色荧光。热评估显示该化合物在 176 °C 之前保持稳定。使用 Z 扫描方法测定了甘氨酸甲酯盐酸盐的三阶非线性光学性质。 GMEHCl的三阶非线性特性β、n ₂和\({\upchi }^{3}\)被确定为1.37 × 10 ^-4  cm/W、3.37 × 10 ^-9 cm ² /W和3.56分别为× 10 ^-6 esu。这一结果表明该晶体可用于各种 NLO 和光子器件配置。
