Ethyl-para-hydroxybenzoate (EHB) single crystals have been grown by slow evaporation solution technique (SEST) using methanol as a solvent. The grown crystal was subjected to single crystal X-ray diffraction analysis, confirming that the crystal belongs to monoclinic structure. The grown crystal was characterized by powder X-ray diffraction analysis. The functional groups present in the EHB crystal have been identified using FTIR spectrum analysis. The laser damage threshold of EHB crystal was measured. The mechanical strength of the grown EHB crystal was measured using Vickers microhardness, no cracks have been observed up to 100 g of load. The optical transparency of the grown EHB crystal has been measured by UV-Vis-NIR spectrophotometer. The refractive index of grown EHB single crystal is 1.6610. The dielectric permittivity and dielectric loss of the EHB single crystal were studied as function of frequency and temperature. The thermogravimetric analysis (TG) and differential thermal analysis (DTA) were studied. The melting point of EHB was 123°C. The luminescence behavior of EHB single crystal has been analyzed by photoluminescence analysis.

In this paper, an organic 4-nitroaniline picrate (4NP) single crystal was grown by solution growth method. Single crystal X-ray diffraction study revealed that grown crystal belongs to orthorhombic system with Pbcn space group. The solid state constants such as plasma energy, Penn gap, Fermi energy and polarizability of 4NP crystal were determined theoretically. The functional groups of the grown crystals were confirmed qualitatively from FTIR spectral analysis. The thermal decomposition and melting point of the crystal were determined from thermogravimetric analysis. The optical absorption and cut-off wavelength of the crystal were determined from UV-visible study. The second harmonic generation (SHG) efficiency of the grown crystal was measured by Kurtz–Perry SHG test using Nd : YAG laser. The laser damage threshold value of the grown crystal was estimated by multi-shot method using 1064 nm laser.

Single crystals of L-tartaric acid (LTA), an organic nonlinear optical material, have been grown using a home-built crystal growth setup (the Moovendaran–Kalyanasundar–Natarajan setup). Crystals of LTA were also grown by the slow evaporation solution technique. These single crystals were characterized using single-crystal X-ray diffraction, high-resolution X-ray diffraction, and IR and UV–Vis–NIR spectroscopy. In addition, measurements of Vickers microhardness, laser damage threshold value and second harmonic generation efficiency are reported. Thermal, dielectric and photoluminescence studies were also carried out.

We concentrate on the low temperature slow solvent evaporation method and characterization of pure and 1, 10 phenanthraline doped KB5 and describe its potential as a non-linear optical material. The grown crystal has been subjected to single crystal X-ray diffraction analysis to identify the unit cell parameters and crystal system. The presence of carbon, hydrogen and oxygen content were confirmed by CHN analysis. The Kurtz’s-Perry powder SHG efficiency was determined for both pure and 1, 10 phenanthraline doped KB5 crystals as 1.6 and 2.2 times than that of pure KDP. Laser damage threshold studies of the pure and doped KB5 crystals have been found to be Q-Switched Nd-YAG laser.

The grown crystals were subjected to powder X-ray diffraction analysis, (PXRD) and it was found that the title compound was crystallized in the orthorhombic crystal system with noncentrosymmetric space group of [Formula: see text]212121. The vibrational frequencies of various functional groups present in the crystal were analyzed using the FTIR spectrum with a wavenumber range between 450 cm[Formula: see text] and 4000 cm[Formula: see text]. The microhardness analysis of the sample revealed that the crystal belongs to the soft material category. Piezoelectric analysis was performed to measure the value of the piezoelectric (d[Formula: see text]) coefficient. Blue light emission of the material was confirmed using the photoluminescence spectrum. Thermal stability of the grown crystal was analyzed using a melting point apparatus and it was found that the LLPNP is stable upto 175[Formula: see text]C. Etching analysis was performed at various durations, in order to identify the surface properties of the LLPNP crystal.

AbstractA novel 4-methylpyridinium 3-nitrophthalate (4MP3NP) was synthesized and the crystals were grown by using slow evaporation method. The structural data of the grown crystal was collected by single crystal X-ray diffraction. It revealed that the 4MP3NP crystal belongs to triclinic crystal system with a space group P1. Structure of the synthesized compound was established using SHELXL 97 program package. The crystalline nature and composition of the grown crystal was established using high resolution X-ray diffraction and FT-IR analyses. UV-Vis transmittance and photoluminescence studies revealed the optical transmission window and electronic transition mechanism of ions, respectively. The laser damage threshold of the grown crystal was estimated by Nd:YAG laser and these results were mutually related to specific heat capacity of the grown crystal. The third-order nonlinear optical susceptibility of the grown crystal was studied by Z-scan technique.
