Abstract: A single crystal of morpholinium oxalate (MO) was grown by the technique of slow evaporation at ambient temperature utilizing water as a solvent. Single crystal XRD reveals the MO crystal belongs to the monoclinic system with a centrosymmetric space group of P21/n. Powder XRD study demonstrates the crystalline quality. HRXRD study illustrates the crystalline perfection of the crystal and it is the key necessity for device fabrication. The optical transmittance (55%), cut-off wavelength (λ = 330 nm) and band gap energy (Eg = 2.61 eV) were determined by optical studies. Laser-induced surface damage threshold (LDT) analysis appraises the aptness of grown crystal for device fabrications and also the surface roughness of the sample was determined. The thermal stability and decomposition of the crystal were studied by thermogravimetric (TG) analysis and it was found that the material was thermally stable up to 179 °C. The various thermodynamical parameters were determined from TG analysis. The dielectric constant ɛ’ and dielectric loss ɛ’’ divulges the electrical properties of MO crystal and the various electronic parameters were also calculated. The nonlinear optical (NLO) behavior and optical limiting property were analyzed from Z-scan technique. Microhardness measurement was executed to recognize the mechanical strength of the MO crystal and its hardness value is 1.65 kg/mm2.

A new nonlinear optical material, l-alanine acetate (l-AlAc) has been synthesized. Single crystals of l-AlAc have been grown by the slow cooling method. Bulk crystals have been grown with a solution pH of 3.0. The grown crystals were subjected to various characterization studies such as chemical etching, dielectric measurement, FTIR analysis, UV-visible spectrum and powder SHG test. The structure of the crystal was confirmed by single-crystal X-ray diffraction analysis. l-AlAc crystals exhibit better thermal and mechanical stability with improved optical properties. © 2004 Elsevier B.V.
