An organic single crystal of Urea Sulphamic Acid crystals (US) was grown by slow evaporation technique at room temperature (30°C). The structure of grown crystal was discovered from the X-ray diffraction study and it belongs to the triclinic system. Vibrational modes of Urea Sulphamic crystal was identified by the employing FTIR spectral analysis. UV-Visible spectral studies showed that the lower cut-off wavelength was found to be 236 nm. The impedance study has been carried out and it was showing a maximum at low frequency and decreases with increasing frequency. The thermal stability of the crystal was determined by employing thermo-gravimetric analysis (TGA) and differential scanning calorimetry (DSC) methods for the grown crystal. Second harmonic generation measurement indicate that the efficiency of urea sulphamic acid nonlinear crystal was 1.1 times greater than that of KDP crystal.The analysis results confirmed that these crystals have better nonlinearity and good mechanical strength.

“…Among the amino acids family, L-histidine molecule consists of the planar imidazole ring in the histidine structure which helps in possessing high nonlinear optical efficiency [11]. A number of L-histidine complexes were reported earlier which shows good NLO property, namely L-histidine maleates [12], L-histidinehydrochloride 13 and Tb 3+ doped L-histidine hydrochloride monohydrate crystal [14]. The electronegative value between boron and oxygen are higher, they can exhibit different structure.…”

A new nonlinear optical crystal L-histidine potassium pentaborate single crystal was grown from aqueous solution by the slow evaporation solution growth technique to analyse its suitability for NLO device applications. It belongs to the orthorhombic crystal system which is confirmed by single crystal X-ray diffraction analysis. The UV-visible analysis was carried out on LHKB 5 crystal to find out cut-off wavelength and the energy gap of the material was found to be 245 nm and 5.05 eV. The presence of L-histidine potassium pentaborate on grown material was confirmed by FTIR analysis. TG-DSC analysis determines that the material has two stages of decomposition and it has three stages of weight loss. From DTA curve a sharp endothermic peak at 192.45°C shows good crystallinity and corresponds to the melting of the grown crystal. The mechanical strength of the material is calculated using Vicker's microhardness. Grown crystal shows that the material is very much suitable for a second harmonic generation and frequency conversion applications.
