“…The salt formation between IND and LYS was again observed in the disappearance of the IND carboxylic acid stretching vibrations at 1710 cm −1 and 1731 cm −1 . Furthermore, the incorporation of the NH 3 deformation at 1504 cm −1 in crystalline LYS[29] into the broad plateau between 1558 cm −1 and 1634 cm −1 upon co‐amorphization suggests the involvement of this group in the salt formation process with IND.…”

“…Also, from the spectrum it is observed that SCTC crystal has lower cut off wavelength around 240 nm and wide transparency window (240–800 nm) of SCTC crystal could be used for UV‐tunable lasers as well as transmission of blue and green harmonic frequency of Nd:YAG laser operating at 1064 nm. The observed cut off wave length of grown crystal is less than the other well known non linear optical crystals like BBO (193 nm) and LBO (159 nm), Ammonium pentaborate (APB) (180 nm), Glycine barium nitrate (GBN) (210 nm), Tryosine doped glycine (200 nm), L‐lysine acetate (236 nm) and γ‐glycine (231 nm) . Interestingly, the result of grown crystal SCTC crystal encourages second harmonic generation and the absence of absorption in the region 240–800 nm is an advantage for NLO applications and also suggesting its use in optoelectronics devices …”

A new inorganic nonlinear optical single crystal of sodium cadmium tetra chloride (SCTC) is successfully grown from aqueous solution by the slow evaporation technique at room temperature. The crystalline nature of the grown crystal is analyzed by powder X‐ray diffraction. The lattice parameters and crystal system is confirmed by single crystal X‐ray diffraction. Optical transmission study on SCTC crystal shows high transmittance in the entire UV–Vis region. The mechanical strength of the grown crystal is estimated by Vicker's microhardness test. The second harmonic generation (SHG) efficiency of the crystal is measured by Kurtz's powder technique infers that the crystal has nonlinear optical (NLO) efficiency 1.75 times that of KDP. The variation of dielectric constant and dielectric loss as a function of log frequency at various temperature reveals that the crystal shows normal dielectric behaviour. The growth process of SCTC crystal is analysed by etching study. The features of surface of grown crystal is analysed by SEM/EDAX spectrum. The third order nonlinear optical property is investigated for the grown crystal by z – scan technique and the results indicates that SCTC crystal should be a promising material for nonlinear optical device applications.

Single crystals of pure and NaCl doped sulphamic acid (SA) were grown by slow evaporation method at room temperature. The lattice parameters and structure were determined by using single crystal and powder X-ray diffraction analyses. The presence of dopant in the SA lattice was affirmed by EDAX analysis. UV-Vis spectra show maximum transmittance in the visible region. The band gap energies were found to be 6.06 eV and 5.70 eV for pure and NaCl doped SA crystals respectively. From the PL specta the emission were observed at 335 and 424 nm for pure and 340 and 428 nm for doped SA crystal. The thermal stability of the grown crystals were analyzed by thermogravimetric and differential thermal analysis (TGA/DTA) and revealed that the grown crystals were thermally stable up to 331 °C and 334 °C for pure and NaCl doped SA. Vickers microhardness study reveals that the hardness of the crystals is increase with increasing load. The photoconductivity study shows that the grown crystals are negative photoconductive nature. The Laser Damage Threshold (LDT) indicates the grown crystals have good resistance to laser radiation than a standard Potassium dihydrogen phosphate (KDP) crystal. The Z-scan technique was employed to determine the nonlinear refractive index, nonlinear optical absorption and third order nonlinear optical (TONLO) susceptibility of the grown crystals using He–Ne laser.
