摘要

采用缓慢蒸发法，在中等温度下培育出了添加了蛋氨酸（LM）的氨基磺酸（SA）晶体。粉末 XRD 图显示，添加了 LM 的 SA（LMSA）晶体具有正方晶体结构。傅立叶变换红外光谱研究证实了各种振动模式的存在。使用紫外可见光谱仪观察了 LMSA 在紫外和可见光范围内的透射率，并计算了 LMSA 的带隙。与纯 SA 相比，LMSA 的硬度值更高。对 LMSA 的光致发光发射研究表明，在 491 纳米和 542 纳米处有发射，这分别是由于从 5D4 态过渡到 7F6 和 7F5 地态。根据其抗菌活性研究，LMSA 晶体能有效杀死病原菌。

Growth, characterization, and anti-bacterial activity of l-methionine supplemented with sulphamic acid single crystals

Sulphamic acid (SA) crystals supplemented with l-methionine (LM) were grown at moderate temperatures using a slow evaporation procedure. The powder XRD pattern showed that LM supplemented with SA (LMSA) crystals have an orthorhombic crystal structure. The FTIR studies confirmed the presence of various vibrational modes. Using a UV-Vis spectrometer, the transmittance of LMSA in the UV and visible range was observed, and the band gap of the LMSA was also calculated. The hardness value of LMSA was higher compared to that of pure SA. Photoluminescence emission studies of LMSA pointed out emissions at 491 and 542 nm, which were attributed to the transition from the 5D4 state to 7F6 and 7F5 ground, respectively. LMSA crystals were effective in killing pathogenic bacteria, according to the studies on their anti-bacterial activity.
