Organic bulk single crystal of cyclohexylaminium hydrogen phthalate hemihydrate (CYHPH) was grown by slow cooling method using methanol as a solvent. The grown crystal belongs to orthorhombic system with Pbcn space group and it has various functional groups such as NH3 +, phthalate and a water molecule. The cut off wavelength of CYHPH was found at 307 nm. Thermal analysis affirmed that the CYHPH compound was stable up to 146 °C and completely decomposed at 263 °C. The activation energy at 100 Hz, 1 and 10 KHz was found to be 0.31, 0.141 and 0.142 eV respectively. The grown CYHPH crystal exhibits third order nonlinear optical behavior. © 2017, Springer Science+Business Media New York.

Organic material of bis(cyclohexylammonium) succinate succinic acid (BCSSA) single crystal was grown by slow evaporation technique at room temperature and bulk of BCSSA was grown by slow cooling method. Single crystal XRD analysis reveals that the BCSSA crystal belongs to the triclinic crystal system with centro-symmetric space group (P1¯) The FT-IR spectrum confirm the functional groups of NH3+, succinate and succinic acid present in the BCSSA crystal, showing the evidence of compound formation and optical band gap was calculated using UV-Vis-NIR analysis. The third order nonlinear optical parameters were calculated by Z scan technique using 532 nm diode pumped CW Nd:YAG Laser and the optical limiting spectrum of BCSSA shows the suitability in optical limiting applications. © 2017 Elsevier B.V.

Single crystal of cyclohexylammonium hydrogen adipate (CYHAD) was grown from slow evaporation solution growth technique. The crystal structure and lattice parameters were determined by single crystal X-ray diffraction analysis. The material crystallized in monoclinic crystal system (P21/c). The FT-IR and CHN analysis were used to conform the functional group present in CYHAD. The material has high transparency with negligible absorption in the entire visible region and the optical band gap was found to be 4.90 eV. The PL spectrum shows the blue emission of CYHAD. The CYHAD crystal was stable up to 168.01 °C and the laser damage threshold of CYHAD was 9.74 GW/cm2. Electrical properties were studied using LCR impedance analyzer. The third order nonlinear properties (n2=-5.124 × 10−8 cm2/W, β = 0.024 × 10−4 cm/W and χ3 = 2.443 × 10−6 esu) were calculated using 532 nm diode pumped CW Nd:YAG Laser and optical limiting behavior endorse that the CYHAD material is favorable for optoelectronic applications. © 2018 Elsevier B.V.

We report the growth and nonlinear optical properties of cyclohexylammonium acetate (CYHAC) crystal. The functional groups and crystal structure were determined using FT-IR analyses and single crystal XRD (293 K). UV–Vis–NIR measures the cutoff wavelength (254 nm) and optical band gap (5.17 eV) of CYHAC crystal. TG-DSC spectrum shows the melting point (161 °C) and decomposition of the compound. Activation energy was calculated from dielectric studies as a function of frequency at different temperatures. Laser damage threshold of CYHAC is 5.23 GW/cm2. Nonlinear optical parameters were calculated using Z-Scan technique for this material and its optical limiting behavior were also tested, the value of limiting threshold and clamping output are 24.3 mW and 7.1 mW respectively. © 2017 Elsevier B.V.

Single crystals of γ-glycine were grown by slow evaporation technique. The crystalline system was confirmed by single crystal X-ray diffraction analysis. The optical absorption study has shown that the grown crystal possesses lower cut-off wavelength. Solubility and metastable zone width were estimated for different temperatures. The induction period of title compound was determined by varying the temperature and concentration. Nucleation parameters such as Gibbs volume free energy change (ΔGv), interfacial tension (γ), critical free energy change of the nucleus (ΔG*), nucleation rate (J), number of molecules in the critical nucleus (i*) have been calculated for the aqueous solution grown γ-glycine single crystals. The second harmonic generation (SHG) of γ-glycine was confirmed by Q-switched Nd:YAG laser technique. © 2013 Elsevier B.V.
