Tuning the Optical, Thermal and Biological Studies of a Pure and Succinic Acid Doped L‐Glutamic Acid Hydrochloride Single Crystal

Abstract One of the non‐essential amino acids, L‐Glutamic Acid Hydrochloride (LGH) and Succinic acid (SA) doped L‐Glutamic Acid Hydrochloride (LGH) is grown by the slow evaporation method. The grown, uncanny LGH and SA: LGH crystal is put through some characterizations like X‐ray diffraction (XRD), UV–vis spectroscopy, Fourier transform infrared (FTIR) spectroscopy, Thermal Gravimetric Analysis (TGA) and Differential Thermal Analysis (DTA) and antimicrobial activity. The successfully grown L‐Glutamic Acid Hydrochloride (LGH) and Succinic acid (SA) doped L‐Glutamic Acid Hydrochloride (LGH) crystal's structure and space group are determined by X‐ray diffraction. From Fourier transform infrared (FTIR) spectroscopy, the fundamental functional group can validated. The optical energy band gap of the semi‐organic crystal of Pure LGH and SA: LGH is calculated by UV–vis spectroscopy. The thermal behavior of the grown crystals are interpreted by Thermal Gravimetric Analysis (TGA) and Differential Thermal Analysis (DTA). An antimicrobial appraisal reveals that the peculiar pure LGH and SA: LGH crystal is used to act against bacterial infections. Grown pure and SA: LGH crystal shows well resisting activity against various fungus such that Candida albicans, Candida parapsilosis,Aspergillus flavus. Eventually, Simple Harmonic Efficiency (SHG) is estimated with KDP crystal.
