“…The selected quantity and the high dipole moment of the dopant glycine results in the observed enhancement of SHG efficiency in the G-BTZA crystal [23,24]. It is noteworthy that glycine is the most suitable dopant as compared to lithium chloride, Cd +2 and L -proline, for achieving high SHG efficiency with the BTZA crystal [9][10][11]. The high SHG efficiency strongly conveys the active utility of the G-BTZA crystal for laser frequency conversion devices.…”

A single crystal of glycine-doped bis-thiourea zinc acetate (G-BTZA) with a dimension of 15 × 6 × 4 mm3 has been grown using the slow solution evaporation technique. The structural parameters of the crystals were determined using the single crystal XRD technique. The increase in optical transparency of the doped BTZA crystal was ascertained in the range of 200 to 900 nm using UV–visible spectral analysis. The improved optical band gap of the G-BTZA crystal is found to be 4.19 eV, and vital optical constants have been calculated using the transmittance data. The influence of glycine on the mechanical parameters of the BTZA crystal has been investigated via microhardness studies. The thermal stability of pure and doped BTZA crystals has been determined by employing the thermogravimetric and differential thermal analysis technique. The improvement in the dielectric properties of the BTZA crystal after the addition of glycine has been evaluated in a temperature range of 30 to 120 °C at a frequency of 100 KHz. The SHG efficiency of the glycine-doped BTZA crystal is found to be much higher than KDP and BTZA crystal material in a Kurtz–Perry powder analysis.

“…The addition of lithium chloride (2mole%) has largely enhanced the SHG efficiency, optical transparency and mechanical stability of BTZA crystals [9]. Metallic impurities such as Cd +2 (4wt%) can raise the induced laser damage threshold, second order NLO behavior, thermal stability and optical transmittance of BTZA crystals [10].…”

Bisthiourea Zinc Acetate (BTZA) a semi organic material has been synthesized by slow evaporation method using water as a solvent. The solubility studies have been carried out in aqueous solution in the temperature range 25 ˚C-45 ˚C. Crystals have been grown from low temperature solution method by slow evaporation of saturated aqueous solution at room temperature. Single Crystal X-ray diffraction study has been carried out to determine the lattice parameter of the grown crystal. The spectral bands have been compared with similar thiourea complexes using FTIR spectrum in the range 400-4000 cm-1. Optical transmittance and absorption percentage of the grown crystal have been measured from UV-Vis studies. The thermal behavior has been investigated by thermogravimetric (TGA) and Differential Thermogram analyses (DTA). The mechanical strength and work hardening coefficient of the grown crystal have been analyzed by Vicker's microhardness method.

“…The amino and salicylic acids are the famous organic material that has been used in the field of fabricating the NLOC. Doping an impurity in the legend acid is the most influential factor in changing the NLOC performance [7]. The properties of NLOC include higher nonlinear efficiencies, transparency in a wide optical region, resistance to laser radiation damage [8].…”

The present research is concentrated on improving the characteristic properties of salicylic acid (SA) within the nonlinear optical crystal. So, the layer-by-layer (LBL) technique was utilized to design and make thin films of nanosized aluminum (III) complex of 3-azo-phenolate salicylic acid (NS Al(III)-3AP-SA) having a high specified surface area with various thicknesses. The synthesized material was deposited on glass and quartz substrates to investigate the structural and optical properties. Characterization of fabricated films was performed using TGA, X-ray, SEM, and FTIR. The prepared NS Al(III)-3AP-SA exhibited a spherical shape with a size between 41–61 nm. The optical transmission spectra were studied in the spectral range of 300 to 1100 nm at room temperature. The refractive index, absorption coefficient, and optical energy gap were determined. It was found that the optical energy gap = 3.78 eV without noticeable variation because of thickness increases. Together with their dependencies on the film thicknesses, the nonlinear and linear optical parameters have been calculated. The results suggest that the assembled NS Al(III)-(3AP-SA) can be categorized as a promising material for the fabrication of nonlinear optical crystal applications.
