The paper reports synthesis and co-crystallization of 5 co-crystal of 4-nitrophenol (4N) with five different monoand diaminopyridines (4-aminopyridine (4AP); 3,4-diaminopyridine (34DAP); 2-amino-6-methylpyridine (26MAP); 2,6-diaminopyridine (26DAP); 2-aminopyridine (2AP)) resulted in five adducts with the molar ratio of components 2:1 in final compounds. X-ray analysis confirms the non-centrosymmetric packing of obtained compounds. Two compounds crystallize in the polar acentric P21 and three compounds crystallize in acentric orthorhombic Pna21 space groups. The comparative studies on the laser induced multiple and single shot damage thresholds of named crystals were carried out using radiation of 1064 nm from Nd:YAG laser with pulse width 10 ns. Obtained results show good laser-induced singleshot and multiple-shot damage threshold values for all studied co-crystals and are found up to 3.64 GW/cm 2 and 1.77 GW/cm 2 respectively.

“…Recent research reveals that, organic materials with aromatic rings having less optical absorption, large band gap, high thermal as well as mechanical stability, less fast response with tailor-made flexibility and higher order of nonlinearity find wide applications in high resolution spectroscopy, laser printing, remote sensing, chemical and biological species detection and optical communication systems [1,2]. Among those, material exhibiting high optical nonlinearity is considered to be a promising aspirant due to its potential usage in nonlinear optical technologies demanding low power laser systems [3,4]. The synthesis and growth of such nonlinear optical materials seems to be a challenge in the fast developing fields of optoelectronics and photonics [5][6][7].…”

An organic non-linear optical material of 4-methylanilinium 3,5-dinitrobenzoate (MADNBA) was synthesized and crystals of MADNBA were grown by employing slow evaporation solution growth technique. The crystal structure was confirmed from Single crystal XRD. Grown crystals were characterized by Powder XRD, UV-Vis-NIR, Photoluminescence and Laser damage threshold measurement studies. Infrared spectroscopy, thermal analysis and microhardness measurement were performed to study the molecular vibration, thermal behaviour and mechanical stability of the grown crystal. Dielectric studies have been performed to evaluate various solid state parameters. From the Kurtz Perry powder technique, it was found that Second harmonic generation efficiency of the obtained compound is 10 times that of the standard potassium dihydrogen phosphate. Z-Scan technique was also carried out to investigate the non-linear activity and optical limiting behaviour of MADNBA crystal. Computational analysis performed upon the optimized geometry of MADNBA molecule using Density Functional Theory confirmed the experimentally determined quantities under a strong theoretical background. Frontier molecular orbital analysis and molecular electrostatic potential analysis were carried out. The non-linear character of the compound was also determined by computing various non-linear optical parameters like dipole moment, polarizability and hyperpolarizability. The first order hyperpolarizability (β) value of the MADNBA molecule was evaluated to be 8 times that of the standard urea molecule. Based on these results, it could be proposed that MADNBA material serves as a potential candidate for frequency doubling, optical limiting and photonic applications in optoelectronics domain.

“…Considerable theoretical and experimental investigations were carried out to understand the microscopic origin of the nonlinear behavior of organic NLO materials. NLO frequency conversion material generally consists of an electron donor, an acceptor, and a conjugated π-system as a bridge providing electronic communication between the donor and the recipient [4,5]. The benefits of organic over inorganic systems include high * E-mail: sureshsagadevan@gmail.com electronic sensitivity resulting from high molecular polarization, fast response time, easy modification through standard synthesis methods and relative ease of device processing.…”

L-cysteine hydrogen fluoride (LCHF) single crystals were grown from aqueous solution. Single crystal X-ray diffraction, FT-IR, UV-Vis-NIR, and TG-DTA were used to test the grown crystals. The specimen dielectric and mechanical behaviors were also studied. Powder X-ray diffraction of the grown crystal was recorded and indexed. The optical properties of the LCHF crystal were determined using UV-Vis spectroscopy. It was found that the optical band gap of LCHF was 4.8 eV. The crystal functional groups were identified using FT-IR. Second harmonic generation (SHG) efficiency of the LCHF was three times higher than that of KDP. The dielectric constant, dielectric loss and AC conductivity were measured at different frequencies and temperatures.
