“…Inorganic material comprehensively utilized in these fields due to their excellent mechanical strength and chemical stability even so the poor nonlinearity. At the same time, the organic materials are posses superior nonlinear optical property, however it is too complicate to grow the material in bulk size [3,4]. Therefore the material researchers search for a new semi-organic NLO material because of their high chemical flexibility, thermal and mechanical stability and outstanding optical nonlinearity [5 -7].…”

Single crystals of sodium para nitro phenol (SPNP) and potassium para nitro phenol (KPNP) was synthesized at room temperature by slow evaporation solution growth technique using ethanol as a solvent upto the size of 12 × 3 × 2 mm3 and 15 × 2 × 2 mm3 respectively. The grown crystals were characterized by UV- Visible, photoluminescence, Kurtz- Perry test, single crystal X-ray diffraction analysis and Vicker’s microhardness studies. Structural identification of grown crystals was done by single crystal X-ray diffraction and it shows both the crystals are belongs to triclinic crystal system. The SPNP and KPNP crystal emits green light radiation as evident from the PL measurement. The UV -Visible study revealed that the grown crystal has high transmission window with cut off wavelength of 207 nm and 208 nm respectively. And also the direct optical band gap was estimated to be 3.23 eV and 3.20 eV using Tauc’s plot. The SHG output of grown crystals was recorded by Kurtz Perry technique and it is found to be nearly five times greater than the reference KDP. The Vickers hardness test confirms the mechanical stability of the material.

“…The interest in the synthesis and characterization of semiorganic crystals has increased in recent decades due to their nonlinear optical (NLO) properties and their potential for application in frequency conversion, optoelectronic devices, data storage, etc. . Semiorganic crystal have been explored and considered to be promising for such application because it can incorporate good properties of both organic and inorganic crystals, such as high NLO properties from the organic crystal and high mechanical straight from the inorganic crystal.…”

Semi organic crystals have been intensively studied aiming applications in nonlinear optical (NLO). Such applicability requires crystals with both high quality and thermal stability, which make the full characterization of this material a topic issue. In this paper, single crystals of L-isoleucine hydrochloride monohydrated (L-Ile.H2O.HCl) was synthesized by slow evaporation technique and characterized by thermal analysis and X-ray diffraction (XRD) measurements. XRD results at 298 K showed that the sample crystallize with the orthorhombic structure, and the lattice parameters obtained by Rietveld refinement were a = 5.873(3)Å, b = 24.814(4)Å, and c = 6.873(5)Å. Thermal analysis measurements shows four decomposition stages between 328 -480 K which were associated with loss of water by desolvation, loss crystallization water and decomposition of L-Ile.HCl. XRD measurements as a function of temperature up to 428 K show an irreversible phase transformation. This transformation was obtained after 32 hours keeping the L-Ile.HCl.H2O sample at 413 K. The analysis shows that phase transformation occurs due to water and chlorine losses without destroy the amino acid carbon chain and in the end of transformation only the precursor amino acid remains. L-Ile.HCl.H2O present low thermal stability and the phase transformation is time and temperature dependent.
