Abstract The semi organic nonlinear optical single crystal of L- Threonine Cadmium acetate Monohydrate (LTCAM) doped Ni 2+ion is prepared by the technique slow evaporation solution growth. The prepared crystal was analysed by XRD, EDAX, UV-Vis- NIR, IR, TG/DTA, Photo Luminescence (PL), VSM and SHG measurements. The SXRD shows the crystal come under the monoclinic crystal system with P21 noncentrosymmetric space group. In the visible and near infrared region the crystal shows good optical response and it is a thermally stable compound. The band gap of the grown crystal was 5.02ev. The functional groups are confirmed by FTIR analysis. The luminescent behaviour of the doped crystal shows its ability as UV filters. The dopant turns its magnetic property in to semi paramagnetic nature.

The crystals N-(2-chlorophenyl)-(1-propanamide) (NCP) appropriate for nonlinear optical (NLO) and electro–optic appliances were grown full-fledged by the slow cooling method. The solubility and metastable zone width range of NCP specimen were studied. The specimen crystallizes in the monoclinic crystal system with noncentrosymmetric space group of P21. The crystal morphology study also elucidates supplementary excellence of the as-grown NCP crystal. The optical precision in the whole visible region was found to be superior for NLO claim. The crystallinity of the full-fledged crystal is determined by etching and HRXRD. Laser harm threshold and photoluminescence studies delegate the grown crystal comprises extremely less imperfections. The mechanical deeds of NCP sample at assorted temperatures were examined to decide the hardness solidity of the grown specimen. The piezoelectric behavior and the comparative second harmonic generation for assorted particle sizes of the material were also deliberate. The third-order nonlinear ocular possessions of NCP crystal specimen were determined by [Formula: see text]-scan method. The optical homogeneity of the solitary crystal was assessed using customized channel spectrum technique. The thermal structures of NCP solitary crystal have been studied using photopyroelectric method. The half-wave voltage of the full-fledged crystal was intended from the electro–optic experimentation. Photoconductivity nature of the grown crystal outlined consummate inducing dipoles due to strong incident radiation and further revealed the nonlinear deeds of the grown material.

SrO-Al2O3 ceramics has prospective applications due to its photo-luminescence and persistent afterglow properties. Sr3Al2O6-SrAl2O4 eutectic glass was prepared by using the aerodynamic levitator equipped with a CO2 laser device. The prepared Sr3Al2O6-SrAl2O4 eutectic glass beads were further heat-treated at temperature from 880°C to 980°C. The phase evolution, crystallization behavior, optical transmittance and mechanical properties of the annealed eutectic glass ceramics were investigated. The as-prepared glass is colorless and transparent over a wide range from ultraviolet to near-infrared region, and the average in-line transmittance is over 80% in the range of 260-3200nm. There were two crystal phases Sr3Al2O6 and SrAl2O4 crystallized from the glass beads. With increasing heat-treatment temperature, the transparency of the samples decreased, and the hardness increased. The prepared Sr3Al2O6-SrAl2O4 eutectic glass and glass ceramics may be a promising candidate for the development of photo-luminescence and persistent afterglow materials.

Nonlinear Optical Properties

In this paper, in order to study the relationship between structure and performance, four new NFA derivatives were designed based on the two reported NFA molecules BO-4Cl and BTP-S2 by replacing the BT unit with a less-electron deficient BTz unit and inserting another ethylene double bond between the central core and the terminal groups. The DFT and TD–DFT calculations were applied to invstigate linear and nonlinear optical properties, such as electronic structure, electronic absorption, reorganization energy and the second-order NLO properties. The investigation demonstrates that they are all narrow bandgap derivatives, the absorption spectrum extends to the near-infrared region and using two ethylene double bond is the most effective way to reduce the energy gap, redshift the maximum absorption peak and the middle absorption band, enhance hole transport ability and weaken electron transport ability and enhance second-order NLO response. Considering the smaller electron and hole reorganization energy and the larger static first hyperpolarizability value, the studied NFA derivatives have great potential to become ambipolar charge transport materials and large second-order NLO materials.

This study investigates near-infrared region Ag2S quantum dots (QDs) and their nonlinear optical response under 532 nm nanosecond laser pulses. Our experimental result shows that nonlinear transmission is reduced from 0.084 to 0.04. The observed narrowing behavior of the output pulse width shows superior optical limiting. We discuss the physical mechanisms responsible for the nonlinear optical response of the QDs. The average size of the nanocrystals was 5.5 nm. Our results suggest the possibility of using these Ag2S QDs for photoelectric, biosensor, optical ranging, and self-adaptive technologies.
