Single crystals of Sodium Oxalate (SO) were grown by adopting the slow evaporation solution growth approach from aqueous solution. The prominent functional groups seen in the SO crystal were distinctly detected with Fourier transform infrared and FT-Raman spectral analysis. The cut-off wavelength of 230 nm was measured using Ultraviolet -visible spectral analysis. Theoretical quantum chemical computations were done by DFT using Gaussian software package. The different properties such as structural, vibrational and electronic properties of SO was studied at the B3LYP/LanL2DZ level. The chemical activity of SO molecule was revealed by HOMO-LUMO energies. From Topology analysis the chemical significance of the molecules has been enunciated. The electron density centered on local reactivity descriptors like Mulliken atomic charges and Fukui function were calculated to describe the chemical reactivity of the SO compound. The mechanical property of the grown crystal was disclosed from Vicker's micro hardness test carried out on the grown SO crystals and the test confirms the soft nature of the crystal. The dielectric behavior of SO crystal was completely investigated for different temperatures and the activation energies were calculated for different frequencies.

Good quality single crystals of organic imidazolium L-Tartrate (IMLT) are grown up from aqueous solution by slow solvent evaporation technique. Various structural parameters and monoclinic crystal structure have been confirmed using powder X-ray diffraction method. The presence of various functional groups has been identified by ATR-FTIR. UV-Vis-NIR spectroscopy has shown more than 60% of optical transparency with the lower UV cutoff at 245nm. The optical band gap value of the material is evaluated to be 4.8 eV. Other optical parameters such as refractive index, optical and electrical conductivity, Urbach energy, extinction coefficient, and optical and electrical susceptibility have been evaluated from transmission spectrum data. The above essential parameters manifest appropriate usage of IMLT as an NLO material. The thermogravimetric analysis indicates high thermal stability of material up to 214°C. Apart from that, the dielectric study at various temperatures confirms decrement of dielectric constant and dielectric loss at higher frequencies. The efficiency of Second Harmonic Generation (SHG) is found to be 3.5 times that of the KDP crystals. A range of analysis suggests suitability and potentiality of IMLT crystal for various optoelectronic applications.

“…Overall, the high transmittance and low refractive index values (n = 0.4) of NdSrPspherulites makes it useful for non-linear optical applications. The electrical susceptibility (χ c )is related to optical constants as given by relation [15] ε r = ε 0 + 4πχ c = n 2 -k 2 (8)…”

The growth of neodymium doped strontium phosphates (NdSrP) materials involves the system Nd (NO 3 ) -SrCl 2 -H 3 PO 4 -Na 2 SiO 3 . The optimum conditions involved for the growth of NdSrP were found out. These are found to be highly efficient laser crystals with good electro-optic and conducting properties. X-ray diffraction (XRD), particle size analyzer, scanning electron microscopy (SEM), ultraviolet spectroscopy (UV), Fourier transform infrared spectroscopy (FTIR), and dielectric studies were performed to characterize the samples. The material belongs to triclinic crystal system with well defined and highly resolved crystalline peaks. The electron micrograph clearly depicts the spherulitic morphology that has further grown in the form of elongated plates. The presence of various atomic bonds within a molecule and the functional groups along with the relevant P -O bonds were found by Fourier transform infrared (FTIR) method. Ultraviolet (UV) spectroscopy is an important technique to explore the optical properties of a given material viz., electronic transitions and optical band gap.The optical transmittance range and transparency cut off depict that material possess enhanced optical characteristics. The electric analysis establishes the material to be normal dielectric and the dielectric constant is strongly temperature and frequency dependent.
