Growth and characterization of glycine doped bis thiourea cadmium chloride single crystal

Abstract

Single crystal of 2 mol% glycine doped Bis Thiourea Cadmium Chloride, a semi organic nonlinear optical material has been grown by slow evaporation technique. Good quality single crystal with dimension 14 × 12 × 5 mm3 was harvested after 35 days. The influence of amino acid glycine was studied for 1, 2 and 3 mol% glycine doped Bis Thiourea Cadmium Chloride by Kurtz and Perry powder second harmonic generation test and compared with pure Bis Thiourea Cadmium Chloride which confirms the enhancement of second harmonic generation property of glycine doped Bis Thiourea Cadmium Chloride. The large enhancement was found for 2 mol% glycine doping. The grown crystal was characterized by various characterizations viz. single crystal X‐ray diffraction, energy dispersive X‐ray (EDAX), Fourier Transform Infrared Spectroscopy (FTIR) analysis, UV‐visible absorption, thermo gravimetric analysis (TGA).

Investigation on the Linear and Nonlinear Optical Properties of L-Lysine Doped Ammonium Dihydrogen Phosphate Crystal for NLO Applications

“…The amino acids are organic materials for NLO application as they have donor carboxylic (COOH) group and the proton acceptor (NH 2 ) amino group, known as zwitter-ions. Therefore, amino acids can be used as dopants and it was observed that there is enhancement in the material properties such as NLO and ferroelectric properties [6]. L-lysine posses a side chain with hydrogen atom which offers to charge transfer to form semiorganic crystals for nonlinear optical applications [7].…”

Synthesis and characterization of a surface-grafted Cd(II) ion-imprinted polymer for selective separation of Cd(II) ion from aqueous solution

“…As expected, all of the polymers exhibited similar spectral profiles. The intense adsorption band at 1729 cm -1 was assigned to carbonyl groups from EGDMA [38], whereas the adsorption band of C=S was observed at 1393 cm -1 [39,40]. The absorption band at 1465 cm -1 can be assigned to N-C-N stretching vibration [39].…”

Optical Properties of Single Crystals

“…Along the phase-matching angle, its SHG efficiency is almost similar to that of urea. It is a promising NLO crystal for different applications in the area of laser and optoelectronic [8,[19][20][21].…”
