“…11 indicates that there is a strong absorption at 338 and 397 nm. This may be due to nitrogen-containing aromatic systems or electronic excitation in this region [48,49]. Essentially, a high energy raises the electrons to higher bands, so the crystal structure absorbs the light, while the light without enough energy to raise the electrons to the following band will pass through the structure.…”

The new organic-inorganic compound, [(C 6 H 7 N 2 O 2) 3 TeCl 5 .2Cl] was synthesized and its structure was determined at room temperature in the triclinic system (P ̅ 1) with the following parameters: a= 10.5330(11)Å, b= 10.6663(11) Å, c= 15.9751(16)Å, α= 82.090(2)°, β= 71.193(2)°, γ= 68.284(2)° and Z = 2. The final cycle of refinement led to R= 0.057 and R w = 0.149. The crystal structure was stabilized by an extensive network of N-H...Cl and nonclassical C-H…Cl hydrogen bonds between the cation and the anionic group. Several thermal analysis techniques such as thermogravimetric analysis, the differential scanning calorimetric analysis and Evolved Gas Analysis were used. We used isoconversional kinetics methods to determine the kinetics parameters. We observe that the decomposition of [C 6 H 7 N 2 O 2 ] 3 TeCl 5 .2Cl entails the formation hydrochloric acid of nitroaniline as volatiles. The infrared spectra were recorded in the 4000-400 cm-1 frequency region. The Raman spectra were recorded in the external region of the anionic sublattice vibration 50-1500 cm-1. The optical band gap was calculated from the UV-Vis absorbance spectra using classical Tauc relation which was found to be 3.12 and 3.67 eV.

Growth of Glycine Rubidium Chloride (GRC) single crystals were grown from aqueous solution by slow evaporation technique.Investigations on nucleation kinetic parameters are very important tools for the successful growth of good quality, transparent and big-sized single crystals. Glycine Rubidium salt was synthesized and solubility studies have been carried out by gravimetric method in the temperature range of 30-50 o C. The induction period of the GRC salt for the selected super saturation ratio at room temperature was measured. The fundamental nucleation parameters such as Gibbs free energy change, interfacial tension, and critical radius, number of molecules in the critical nucleus and nucleation rate were calculated for GRC sample for the first time based on the classical theory of nucleation. The grown crystals were characterized by X-ray diffraction analyses. The important optical parameters such as absorption coefficient, extinction coefficient, refractiveindex, optical band gap, optical conductivity and electrical conductivity were estimated from UV-vis-NIRspectral analysis to study the linear optical behavior of the material. Fourier transform infrared (FTIR) study was used to confirm the presence of various functional groups in the grown crystal. The TG and DTA analyses ensure that the material is thermally stable up to 222 0 C. The hardness parameters such as microhardness number, work hardening coefficient, yield strength and elastic stiffness constant of the grown GRC crystals were calculated from microhardness studies. Second harmonic efficiency (SHG) of the grown material is 1.1866 times as that of KDP crystal. The third-order nonlinearities of GRC crystal have been investigated by Z-scan method. The values of nonlinear refractive index (n 2),
