Abstract

Single crystals of L-alanine and Lithium sulfate doped L-alanine crystals were successfully grown by the slow evaporation method. The powder XRD studies were used to analyze the crystalline nature of the crystals. ICP analysis confirms the presence of lithium in the grown L-alanine crystal. The optical bandgap of grown crystals was measured by UV–Vis spectroscopy, and different functional groups present in the grown crystals have been identified by the FTIR spectral analysis. The dielectric studies of the grown crystals were performed at different temperatures as a function of the frequency. The photoconductivity study contributed its positive photoconducting nature. The second harmonic generation for the grown crystal was confirmed by the Kurtz–Perry technique.

摘要

L-丙氨酸单晶和硫酸锂掺杂的L-丙氨酸晶体通过缓慢蒸发法成功生长。粉末 XRD 研究用于分析晶体的结晶性质。ICP 分析证实在生长的 L-丙氨酸晶体中存在锂。通过 UV-Vis 光谱测量生长晶体的光学带隙，并通过 FTIR 光谱分析识别生长晶体中存在的不同官能团。生长晶体的介电​​研究是在不同温度下作为频率的函数进行的。光电导研究贡献了其正光电导性质。Kurtz-Perry 技术证实了生长晶体的二次谐波产生。
