“…An UV-Vis-NIR spectral study is useful to determine the transparency of a material, which is an important requirement for the material to be optically active [26]. A sample absorbed light of a wavelength in the UV region for the transition of an electron from a lower energy level to a higher energy level and was not absorbed in the visible and near-infrared regions of incident electromagnetic radiation [27]. The UV-Vis-NIR spectrum of BLSOD is shown in Fig.…”

From the raw materials L-Serine and oxalic acid, the product Bis-LSeriniumoxalatedehydrate(BLSOD) was created. By using a slow evaporation process, the individual BLSOD crystals were produced from aqueous solution. According to single crystal X-ray Diffraction investigations, the structure of the produced crystal is monoclinic. The existence of different functional groups and the chemical environment present in the synthesised material were qualitatively determined through the use of Fourier Transform Infra-Red (FTIR) and proton nuclear magnetic resonance (H1NMR) spectrum studies. The crystal's transparency in the visible and near-infra-red areas was confirmed by UV-Visible-Near infrared and photoluminescence spectrum tests, which also looked at the material's viability for device construction. To determine the crystal's machinability, the mechanical properties of the material were carefully examined using Vicker's hardness research. Thermal investigations such as Thermo gravimetric (TGA) and Differential thermal analysis (DTA) have shown the thermal stability of BLSOD and the phases of weight losses. As a function of frequency and temperature, the dielectric constant and dielectric loss of grown crystals were determined. The Kurtz-Perry powder test was used to check both the second harmonic generation (SHG) and then the NLO property of the material.

Ultraviolet Light Effects on Cobalt–Thiourea Complexes Crystallization

et al. 2021

In this work, a cobalt–thiourea complexes crystal synthesis was carried out comparatively with and without ultraviolet light assistance (λ = 253 nm), and its effect was studied. Through the solvent evaporation technique, crystalline forms were obtained, which were analyzed and characterized by different techniques: Raman spectroscopy, X-ray diffraction (XRD), and digital optical microscopy. Crystal’s shape changes were observed when comparing those obtained from the solution with and without ultraviolet (UV) assistance. It was found that the UV light effect on the crystals causes a structural modification of the complex synthesized in the (022) (120) planes and without UV assistance in the (002), (111), (131¯), and (132¯) planes. It is also possible to observe an increase in intensity by Raman spectra identified as Co–S bonds (297 cm−1) for crystals synthesized with UV assistance.
