“…For KDP the values along different symmetry axes range between 1.36 and 8.34 Â 10 À14 esu whereas those for BBO vary in the range of 2.4-4.62 Â 10 À14 esu. 42,43 The c (3) values of rGO-ZnSe and rGO-ZnTe composites compare well with these nonlinear crystals. These values are better when the use of fs laser pulses for our measurements is considered.…”

“…In table 6, the results of 4M1PMS and 4BPMS were compared with organic/inorganic/thin films based materials. It is noted that the value of c 3 ( ) is reasonably larger than that for small conjugation based organic molecular system [50,66,67] but two-fold magnitude order greater than those for inorganic materials [68,69]. Furthermore, results are comparable with organic/ organometallic based thin films and dyes materials [70][71][72][73].…”

In the present work, growth of single crystals of chalcone derivatives {4-[(1E)-3-(4-methylphenyl)-3oxoprop-1-en-1-yl]phenyl 4-methylbenzene-1-sulfonate} (4M1PMS) and {4-[(1E)-3-(4-bromophenyl)-3-oxoprop-1-en-1-yl]phenyl4-methylbenzene-1-sulfonate} (4BPMS), at room temperature is reported. The spectroscopic techniques are used to identify the presence of functional groups in the materials. The single-crystal XRD and powder XRD analysis reveals that 4M1PMS belongs to noncentrosymmetric (P2 2 2 1 1 1 ) and 4BPMS belongs to centrosymmetric P n 2 1 ( ) / crystalline system. The molecular structures exhibit C-HKO and π...π intermolecular interactions. From UV/VIS/NIR spectroscopic studies, it is found that both samples have bathochromic shifts in linear absorbance (cut-off region) spectra. The broad emission region involved in several sharp emission peaks in blue region, exhibits a blue light emission property, as observed from photoluminescence study, in both the samples. The thermal stability of the materials were studied by TGA/DTA techniques and crystals were thermally stable until the melting point. In NLO study, 4M1PMS crystal has shown SHG efficiency 2.2 times that of KDP crystal. In addition, electronic contribution in hyperpolarizability (first order and second order) tensors of both the compounds were computed theoretically by M06-2X functional at DFT level. The open/closed aperture Z-scan technique were performed to evaluate third order nonlinear optical materials by measuring experimental parameters such as nonlinear absorption/refraction and calculate second-order hyperpolarizability with corresponding third-order nonlinear optical susceptibility c 3 ( ) ( ) of 4M1PMS and 4BPMS. The surface damage threshold studies of 4M1PMS and 4BPMS were performed by Q-switched Nd:YAG laser at 532 nm.

“…However, in the form single crystals are most important for wide range of optoelectronic applications such as laser harmonic generations (SHG, THG, 4HG), sum or difference frequency generation (SFG, DFG) and etc. [1][2]. The development of photonics and optoelectronic technologies rely heavily on the growth of NLO materials with quick responses.…”

Optical high quality semi-organic piperazinium tetrachlorozincate monohydrate, [C4H12N2] ZnCl4. H2O (PTCZ) single crystals were grown by conventional solution method. The structure of grown crystal was confirmed by the single crystal X-ray diffraction (SXRD) analysis. The material phase purities and its various (hkl) planes have been confirmed by the powder X-ray diffraction (PXRD) analysis at room temperature. The different functional groups were confirmed by the Fourier-transform infrared (FTIR) spectroscopy. The optical quality of the PTCZ single crystal and band gap energy have been identified by the UV-Vis NIR spectral analysis and also calculated refractive index of the material. The thermal stability of the PTCZ single crystal was investigated by TG-DTA. The hardness related properties were analyzed by microhardness tester. The dielectric properties have been measured on the grown single crystal and the electronic polarizability value has been calculated with various theoretical approach. The etching process was carried out on the grown crystal to finding the dislocation density. The crystal atomic perfection has been investigated by the high resolution X-ray diffraction (HRXRD) or Rocking curve (RC) analysis. The Z-scan measurement has been carried out to finding third-order optical susceptibility (χ(3)) of the grown single crystal using solid state laser (640 nm).
