“…However, only one report is available in which the doping of L-arginine in KDP was done (Kumaresan et al 2004) and the SHG efficiency is reported to be increased by doping of L-arginine. Moreover, the effect of doping of amino acids, L-tyrosine (Meera et al 2001), and L-lysine (Mohan Kumar et al 2001), in TGS crystals has been investigated. Figures 2-4 show the powder XRD patterns of pure KDP, 0⋅3% L-arginine doped KDP crystals and 0⋅4% Larginine doped KDP crystals, respectively.…”

Potassium dihydrogen phosphate (KDP) is a well known nonlinear optical (NLO) material with different applications. Since most of the amino acids exhibit NLO property, it is of interest to dope them in KDP. In the present study, amino acid L-arginine was doped in KDP. The doping of L-arginine was confirmed by FT-IR and paper chromatography. Thermogravimetry suggested that as the amount of doping increases the thermal stability decreases as well as the value of thermodynamic and kinetic parameters decreases. The second harmonic generation (SHG) efficiency of L-arginine doped KDP crystals was found to be increasing with doping concentration of L-arginine. The results are discussed here.

“…All ferroelectric materials are pyro electric, however, not all pyro electric materials are ferroelectric. Below Curie temperature, ferroelectric and pyro electric materials are polar and possess a spontaneous polarization or electric dipole moment [4][5][6][7]. However, this polarity can be reoriented or reversed fully or partially through the application of an electric field with ferroelectric materials.…”

Triglycine sulphate (TGS), an important ferroelectric material has been widely used in the fabrication of high sensitivity infrared detectors at room temperature. Single crystals of KDP doped TGS was grown by slow evaporation method at room temperature in this study. The grown crystal was characterized by UV-Vis spectroscopy, FTIR spectroscopy, powder X-ray diffraction studies, and ferroelectric studies. KDP doped TGS crystals were found to be highly transparent and full faced. The experimental results evidence the suitability of the grown crystal for optoelectronic applications.

“…HRXRD results of pure TGS crystals have not been reported earlier. However, 18 arc sec has been reported for L-cystein doped [16] and 16 arc sec for L-tyrosine doped TGS crystal [17]. It may be mentioned here that such low angle boundaries could be detected with well-resolved peaks in the diffraction curve only because of the high-resolution of the multicrystal X-ray diffractometer used in the present studies.…”

The recently discovered crystal growth method called uniaxially solution-crystallization method of Sankaranarayanan-Ramasamy (SR) is modified in some aspects and used for growth of triglycine sulphate (TGS) crystals. The modification leads to the simplicity, reduction of cost and avoided the temperature fluctuations. The <010> direction of TGS is very important and used for fabrication of infrared detectors. Using this method, the <001>, <010> directional crystals of TGS were successfully grown in a glass crystallizer. The grown crystal was characterized by HRXRD, UV-Visible and dielectric studies. The results prove the suitability of the modified SR method for oriented TGS crystal.
