Crystal Growth, Synthesis, Structure, EDAX, UV-Vis-NIR, Band Gap Energy, XRD, and Thermal Studies of L-Proline 4-Nitrophenolate Crystal: A New Semi-organic Compound (L-PNP)

L-proline 4-nitrophenolate crystal (L-PNP) uses a mixture of deionized water and ethanol as solvents for manufacturing a semi-organic nonlinear optical material. The crystal that was produced using the method suggested had been subjected to characterization investigations. The crystalline type of synthetic crystals may have been identified using an XRD pattern. X-ray diffraction study on a crystal confirmed the crystal structure. The results of infrared spectroscopy investigations were used to identify the several functional groups that the growing crystal contains. The transparency of the formed crystal was studied using UV-Vis-NIR spectrum analysis. The newly formed crystal’s lower cut-off wavelength was determined at 360 nanometers. The made crystal’s fluorescence spectrum testing showed an emission peak at 457 nm. The (L-PNP) Up to 140 °C, the material is stable, based on the TG/differential thermal analysis (DTA) curves that have been used to determine its thermal stability. A wavelength of 3.125 eV has been established for the band gap energy. Furthermore, the shape of these synthetic crystals was verified using a scanning electron microscope (SEM). Considering the detection technique known as the energy dispersive X-ray (EDAX), the maximum adsorption sites on an L-proline 4-nitrophenolate crystal were identified. The final results of all studies have been compared with those obtained using pure (L-PNP) crystals.
